If you're not looking for "aquarium grade", you probably could still find it at Michaels or JoAnne Fabrics (going out of business?). Should just be "polyester batting", and with the thickness we're usually looking for, probably for quilting.

LiveAquaria has really dropped in quality in the last year or two, my last order, more than a year ago, arrived without even a styrofoam box, just loose packed in some crumpled paper (no additional bag around the fish bags either) with a heat pack. The bags were in the 50s, the cardboard box was thin (no impact protection), the crumpled paper was wet, and when I went to post about it on reef2reef, the responses I got were all similar experiences/sentiments. I hope they turn themselves around, but they are certainly not the quality they once were.

Another 18 days in, same larva (and still have the other one, it's just still smaller too.)

A baffle like a PVC pipe (or maybe if you need a flat side, a cleaned out food container with the bottom removed) should do well, just takes up some space and could potentially jam with certain critters getting into it (big snails.) You'd want it to extend an inch or two below the float (minimum, no max) to make sure any direct current was blocked, and you want it open on the top to prevent siphon related issues (not just an inverted cup.) Worth mentioning that it probably shouldn't be the long term solution, mechanical float valves have a few failure modes that makes them dump a lot of freshwater into your tank and they generally aren't known to be super reliable. If regularly inspected/replaced, they can probably work, but an electrical sensor with a backup sensor is a much more robust solution.

I don't know if it helps to catch both. She will protect him, but in isolation or with friendly tankmates that's not necessary, and it's quite beneficial for her to continue to eat a lot (helps grow the next batch) while he won't eat at all, so it made more sense to me to just catch him (and closer to hatch was my preference.) She may actually be more territorial/aggressive with him around carrying the eggs - mine has certainly mellowed out since losing her mate, and the peak of her acting like queen of the tank was always the time shortly before spawning and then I think near hatch.

I lost my male a year or more ago and that ended it. Still have the female, and spotted a fire shrimp one morning holding a full clutch of banggai eggs, so I am considering getting another male to introduce to her. He did start getting wise to my catching techniques after a few batches, though he also chilled out a little more and was a little easier to read (whether he was done spitting them out) the more times I did it.

Gonis have been a mixed bag for me too, the red one has always been happy, basically, and has either had long polyp extension or longer polyp extension. The green one in front is a somewhat lesser version of that. The nearly white nub sticking out behind the confusa on the right of the tank is actually a red short tentacle goni that for months now has looked bleached - pastel neon pink with some polyps, literally clear for others, but still extending... The red one has recently shaded out another short tentacle goni, and I had a couple others that didn't make it through some parameter swings or were put in too high lighting (it seems from my experience that short tentacle gonis don't like as much light), and I'm supplementing a small amount of manganese (not as regular as I should and no ICP in the last few months), that while I'm not certain is doing much, may have helped some of the ones with troubles hang on. As for SPS, I think this tank is gradually coming around too. I think my algae dosing was a bit a problem before - not actually doing it, but that I was overfertilizing the cultures and then dumping nutrients into the tank - and for a long time the monti top center was barely holding on. It's definitely happier, and it has some color (like the reddish acro on the left of it), but both only started getting happier in the last few months. I think it's probably also parameter stability related, since I had the calcium and alk swings due to dosing pump issues and not testing enough to catch them quickly.

It's been a while! The tank has been going along, largely happily, and is about a week shy of four years old now. A lot is unrecognizable, the coral cover is getting to a pretty good spot (trimming and warfare are common), but I've got some long time residents that seem to still be happy (including at least one hitchhiker pistol shrimp that still lives in tunnels under the rocks.) There have been too many events and changes to document, but some of the more recent ones include a crazing rigid airline in the vodka causing an air leak that stopped dosing for a bit (acrylic crazes in alcohol! polycarbonate does not!), a crack in the interface with the flexible airline in the soda ash doser that slowed that substantially (and let the alk swing down), the subsequent corrections to get it back in line, and in reference to above, a custom 3d printed algae scrubber which has been working pretty alright. As for issues, I've got one little stick frag that still isn't growing despite being in there for months, I have to clean the glass from film algae pretty much every day (maybe this is because of high phosphate, but a most-of-a-week long lanthanum chloride regimen didn't seem to do much), and these little clove polyps which look OK but have covered the majority of the rockwork and encrust over semi healthy corals. Not too much in terms of equipment failure, but I did lose a Nero 5 which I ended up just replacing. Still planning on opening the electronics package, but have a pile of other things to do. Oh, and I guess the fact that the red goni ended up with like 3.5" or more of tentacle length and started stinging all of its neighbors, then I corrected some parameters and they're probably past 5" now - not ideal in a tank that's like 18" front to back The pair of yellow banded possum wrasses spawn nightly, the mandarins I don't see spawning much now. The peppermints and skunk cleaners are still spawning but it looks a little less frequent than before, and if the fire cleaners are, I've been missing them. The banggai I have is still the same female and a few weeks ago I actually saw a fire cleaner holding a banggai egg mass, so I suppose I should find her a buddy, and the CBB and pintail wrasse bicker a little bit but seem to be good buddies. Green porites are more aggressive than darth maul porities

+1 to the above. No need to try and take things out when you're growing out the microbiome and are minimally feeding. I'd probably start with the skimmer around your first fish, and may actually wait for chemical filtration another little bit after that. I believe chemipure is supposed to take more stuff than carbon out - some of the inorganic metals and things - but there's a bunch of overlap. Both is probably the most comprehensive option, but just ROX carbon may still be plenty adequate, and if your stocking isn't too heavy and your water changes are somewhat regular, you may be fine with neither, though you'll have some water clarity benefits from it too.

Been a while, never fully stopped though. My methods and equipment are pretty dramatically different (raising in a bucket, feeding mostly artemia nauplii), but while I had had some batches get to about a month old before, I've got two which are a month and a half old! This is the larger of the two, and they are VERY lanky

It's not really physically possible to lose that much salt without being able to notice it - you should be seeing condensates or exported saltwater that would be 20% of the total volume for a 20% salinity drop, and I'm not sure just sucking all the alkalinity, calcium, and magnesium out of it would even account for everything. You say you've rechecked your refractometer, but have you checked another tank with it right before/after your measurement of this tank/this new water? Are the lighting conditions similar for the tests (for the see through type) and is the temperature of the tanks similar? Everything I can think of points towards measurement error (and entirely possible the hardware's fault), but perhaps it's something like the initial measurement is being elevated somehow and it's settling to the lower value? Are the directions on the new salt right in line with the old one (salinity should be the same with the same measured mass of salt added regardless of the composition as long as its all dissolving)?

Sorry to hear, I enjoyed my trip in a few months back and thought you made good use of the space available. I'll see if I can stop in this weekend.

Not exactly a match for the finish, but if you have a 3d printer, I made some internal angles for the BRS screen profiles too: https://www.thingiverse.com/thing:5397399 When dealing with an internal corner using these connectors (or commercial ones) if the length of the connector that fits into the aluminum extrusion is more than half the length of the section, they will collide and not fit all the way. You can trim them with larger wire cutters (or similar), but they may need a little glue to really fit well. I think Red Sea makes some cutouts of preset sizes that are all one piece, so you don't need to worry about how much the adapters fit into an extrusion, but they may not be compatible with the BRS screen extrusions.

I haven't, I imagine it's not an option at all for free swimming larvae, but the eggs may be durable enough to withstand it. Do you think this would be like a few minutes of a bath with relatively low concentration like a coral dip?

Any ideas for hydroid control in larval tanks? I've lost a fair number of runs because some small amount of hydroids got into my egg or larva collection water or, when trying to raise them in-tank, from some getting in through another means and taking hold in the area for the larva. It's sort of a perfect storm of very sensitive organisms (high flow and predators aren't an option) you want to keep and very high food availability, so I guess is there any recommendations to check for or otherwise clean a sample or a vessel to reduce the chances of them growing in early?

From what I've seen from fireworm images, they are much more red/orange and have a much brighter pattern (more contrast). I'd think that's a regular one - had a few sort of pink ones with oranger bits myself.

There's next to nothing that's truly effective in a very small tank that's a HOB, at least from when I looked. There is the QQ1 which is one of the few that don't have garbage reviews, but generally, for small tanks, there seem to be few skimmer options because the best option is always water changes. Even then, the few options there are, are internal, not external.

Have you looked at the Tunze Comline DOC line? On the more expensive side, but while in-sump, they have a very small footprint - I think the 9004 will fit in many AIO rear chambers. Especially if you can find a deal on them, they're known to run well too.

I've got a random smattering of a UPS on both tanks, LiFePo battery packs, a 100W solar cell, a 12V lead acid battery, and an air bubbler. All told, it's probably most of a day of circulation with some heat, then another day or two of just air without any recharging, but the car or sun could be used to get some extra charge. It's not especially robust of a plan, but it doesn't involve too much equipment and can be configured a whole bunch of ways. Without me in attendance, I figure I only have around 4 hours of circulation that automatically kicks in, and then probably only an hour or so worth dissolved oxygen in the tanks until that becomes a problem, and that's the part I'm more concerned about. Hoping some LiFePo UPSs come along at a reasonable price point so I don't have to DIY (can't whole-house a system when you rent.)

They work fine, but they are entirely open - direct access to the internal components for drops of water and direct access to mains contacts for fingers. For this sort of application, I'd go with a power brick like the original manufacturer one (or just chop off and replace the connector on the original one.) For a roughly equivalent enclosed part, you could look at MeanWell's GST series. Not sure if your light will be dimmable. Basically, if it's only a string of LEDs, it should be, but if there's any kind of controller element or power converter (and with only 36V input, this may certainly be the case), the PWM dimming wouldn't have any functionality.

Strange fault, at 4A those contacts shouldn't really be subject to a lot of heating as they're usually not that small. Wonder if there was some gunk in the connector when it was attached or something on the far end shorted and the power supply doesn't have overcurrent protection. In any case, while a replacement original connector on both sides is probably the most elegant solution, if you're going to replace both anyways, you could use virtually any waterproof connector rated for more than 4A (or several contacts that together add up to well over 4A) and just use that instead.

You think it's ich and not lymphocystis? The latter happens primarily as nodules on the fins and can often be a sort of stress response for more sensitive fish. But yes, the treatments I know of are not invert safe (except for tank transfer method, but that's not for a whole tank, it's for individual animals). For treatment, you would remove and treat the fish (probably all together), then I would crank the heat a couple of degrees to reduce the fallow time and wait out the reproduction cycle of the cysts in the DT.

It was likely since the cancellation of this year's MACNA, but it's too bad to see it happen. A staple of learning in our community gone by the wayside. I got so much out of the recorded talks from MACNAs and would have liked to see some in person, I hope another organization can take up the mantle in some form (MARCNA of last year as an example of a similar sort of thing done online with a much reduced budget.)

I don't know how compatible the pipefish are with the anemones in particular, and while I've heard they an do well in mixed reef tanks even with high flow, I haven't really had that experience (though mine is limited and with different species), where they don't seem to do well in high flow and need a fair bit of maneuvering room (the front half of the body is basically straight, only the back half can bend much). I would think the dragonet would be no problem - an established 90 gallon tank with rock and substrate and no other dedicated pod eaters would suggest plenty of food to me - but the easy way to make sure would be to train it onto prepared foods. I've had good luck with frozen, and it typically takes 2-3 weeks of training period, but I've heard of longer term in-tank methods that use pellets (Marc Levenson describes using a glass bottle with a narrow enough neck to keep other fish out). I've heard mixed things about the cardinals too, but I've always liked the nonstandard varieties. I think if you have adequate space for them to hide (crevasses and overhangs, but not necessarily caves), they will probably be fine, but I've kept a very cryptic variety that was often tough to spot with the lights on even in a tiny tank (red stop light cardinals in this case.) Of course the more standard banggais or orbic cardinals would work, but the orbic cardinals can get very large (and are long lived), though a 90G would be plenty of space since they aren't active swimmers. I'd second a fairy or flasher wrasse, the ones I've had have been very fun. I saw a pintail wrasse in a local shop just last week and despaired that my tank is half the size it ought to be for one - but you've got the space! Full sized cleaner shrimp would probably work - I haven't kept any with sexies long term, though - but some of the other anemone or cleaner shrimp can be fun, though perhaps a bit hard to see in that size of tank. If you want small fish with personality, I'd also recommend a sharknose goby (or two), a clown goby, and something like a hector's goby. The latter will just ignore you and be out doing its thing constantly, but the clown goby has the confidence of a fish 10x its size and likes to be out and visible, while the sharknose gobies will show cleaning behavior towards you at least sometimes and do an adorable wiggle before swimming over. If you have any aiptasia and want something interesting, a filefish or a copperband could both be fun additions - the copperbands do have a reputation of being hard to get eating, but mine has a ton of personality (closest to a dog I have in my tank right now) and of course great color.

Sorry to hear. While it's likely not the thing you want to hear, I don't think you'll do find any companies doing in-situ leak repair, once the integrity of the seam is compromised, it cannot be repaired to a similar strength, so a "repair" would involve fully removing the panel, cleaning the edges, and resilliconing the whole thing. If the leak is very small, maybe there's an option, and temporary measures (like a big clamp with appropriate protection for the glass) can help mitigate the issue in the short term and prevent it from getting out of hand, I think replacement is likely your best option.
