Figured I'd close the loop on this one. Spolier: it wasn't the power supply. I traded a few more troubleshooting emails and videos with Kessil and then they decided to replace the light for free as they deemed it a manufacturing defect. The new light came in and I sent the old one back - all on their dime. Just wow. I don't think they owed me anything given the light's age and that I bought it from someone in WAMAS back in mid 2022 - not even an authorized dealer. I figured at best they would offer me a fair deal on a refurb unit and not a free new light, so Kessil definitely gets a deep tip of the hat from me!

Been trading emails with Kessil. It's possible the power supply is failing. Anyone have an AP9X or 500x that I could plug into to confirm? I asked Kessil about any risk to another power supply and they've never seen an occurrence of the light unit causing a power supply failure if that's any consideration.

I've had my AP9X running well for 32 months, but this afternoon I noticed it was off. I turned the power supply off and back on as the light wasn't accessible via the app. The light came on and then went back off after a second. I did this a few times repeatedly with the same results. I tried a factory reset, but was only able to get through the wifi setup manually (QR code did not work) to join the light's network. However even after getting it "connected" to my wifi, I am still not able to connect to it via the app, and it is not showing up as a device on my router. Seems like there is some kind of fault I cannot troubleshoot. It's out of warranty, but I reached out to Kessil about this. Doesn't seem to be a lot of options here to get it back up and running even in a "dumb" mode since the buttons don't do anything.

Macro algae does grow, though I did go through a couple swings where a lot of it was smothered by hair algae. I am not against getting a few more fish. They are more fun than dosing.

Didn't want to call you out by name initially, but your tanks are definitely some of the most successful dosed tanks I've seen, Aaron!

It's a "300 liter" system, but really the tank is about a 65 with a 15 gallon sump. Here's a rough list: 2x ocellaris clowns 2x banggai cardinals 2x mandarins 1x royal gramma 1x midas blenny 1x purple firefish 1x yellow watchman goby 1x yellow clown goby 1x pistol shrimp 1x porcelain crab 1x cleaner shrimp 1x peppermint shrimp 2x rbta I've got a mix of SPS/LPS/softy, including a pretty large blue ridge coral. Frogskin, monti cap, branching monti, dragon fruit monti, xenia, gsp, gorgonian, galaxea, sinularia, clove polyps, hammer, torch, mushrooms, zoas, palys, acans. It sounds like a lot, but it's mostly a bunch of small frags that I've mostly been waiting to grow out to no avail. Nothing is really that big, and I have a fair amount of room to grow out. I've lost a few frags recently, including a very nice toadstool and an ice tort. Most frags tend to fade a few days after I introduce them into my tank.

Following on from my last post about Alk and ULN, I've got my Alk under control, but my nutrients are lower than ever. PO4 has always measured 0.0, and NO3 is now down to 1.3. I've increased my frozen fish feedings (still just once a day) but portion sizes are a bit bigger, I have been feeding corals 3-4 times a week, changing my filter socks only once a week, and my refugium now only runs for 7 hours a day instead of 12. I could start scheduling my skimmer to only run part of the day, take out my filter socks completely, or just start throwing in Costco sized pieces of fish, but I think I'd rather dose what I feel like I'm missing - nitrate and phosphate. I've met a couple people who do, but for some reason this seems unpopular. Is it? I'm considering buying some Trisodium Phosphate on Amazon for Phosphate, and using some Brightwell NeoNitro I got from a fellow reefer for nitrate. Is 16:1 nitrate:phosphate a good ratio?

Sounds like even 10 is "high" alk. Seems like running the higher nutrients necessary to also run high alk seem to be risky since algae can also bloom under higher nutrients. I did see a bump in phosphates by feeding coral twice a week so that'll be my plan for now. Hopefully any increase in algae is controlled by the snails I added back in December.

I have what I think is a ULNS with my nitrate at 1.82 and phosphate currently at 0.0, each measured on a Hanna low range checkers. My Alk is 10.1 but has been as high as 10.7. I'd been raising it from 7 over the course of a few weeks in hopes of getting better growth, however my SPS are starting to burn and fade. My salinity has also crept up to 1.027 recently (usually 1.026) and I am also currently acclimating from 50-150 PAR to 150-250 over the course of a month (currently 10 days in). So I have a lot of variables changing at once since they are all out of whack. Anyway, I think nutrients are a problem that I do not yet have a solution for. I've read that a ULNS shouldn't have high alk, but what's considered high for ULNS? I've read anything between 7 and 12 is acceptable. I'm a little higher than halfway, but given my current state of affairs, I think I need to change things up. To add nutrients, I am planning to feed a bit heavier - currently only feeding corals once a week (up to twice) and will give the fish a little more LRS each day. In the meantime I'm curious to know what a good alk value is for my current nutrient levels.

I didn't think high alk was a problem unless you were also going through the early stages of a tank with ammonia present (kills fish), or if you have an ultra low nutrient system (burns tips). Either way, 11.7 is not very high. I've seen that 12 dKH is usually a suggested upper limit, but I've also seen some people run even higher than that. Bottom line, I wouldn't worry about your alk right now and let it come down naturally if you'd like to run it lower. Not sure about lowering alk, but BRS recommends only raising alk by 1.4 dkh or less in a day. More importantly, I would check on your dosing setup. I also rely on dosing pumps for water changes and additives, but they are really the only things that have screwed up my tank when there's a fault. And faults are not always as obvious as a pump or line leaking. But because I know how lazy I am, they are a necessary evil. Checking on them is less work than actually doing work.

I was able to borrow the club's PAR meter this weekend (thanks again Craig!) and I found out that PAR values for my tank were suuuper low. Most were in the range of 50-125. I have an AP9X over my 3 foot tank, tilted slightly to reduce glare into my eyes when sitting close to the tank. I recently raised it to 17" over the water to get better distribution after watching the recent BRS video: I knew this would reduce PAR output, but I never really knew how much I was getting. I ran the lights at a max of 45% based on what I've seen others do, partially out of paranoia from "cooking" my corals, but I really wanted some real data with the lights. Anyway, as I mentioned, my PAR was very low which probably explains the almost non-existent growth I've experienced. At 100% I recorded PAR values of 100-250 which I think will be great for my mixed reef. That all said, I am currently using the Kessil acclimation function of the light to ramp up to 100% over a 30 day period, starting at 45%. While it doesn't seem like a long time, is this too aggressive? Could I be more aggressive in ramping?

Nice, mandarins are my favorite. If you haven't already, see about establishing a refugium in your sump as a "kitchen" for copepods to grow. You may want to pick up some pods and/or some chaeto to seed it. Mandarins rarely eat prepared food and generally just eat pods, but they will slowly starve after they plow through all the pods in your DT.

Yellow clown gobies are smalll and some of my favorite fish though I've not had much luck finding one lately.

I battled hair algae for a couple months before picking up a more robust CUC. BRK's recommendation of Mexican turbo snails was right on. I do AWCs of about 1.5% a day. A refugium on a reverse light cycle also helps. How old is your tank?

I'm guessing you've picked out some fish by now, but we've got similar tanks. I'd recommend getting a new goby if your watchman hasn't turned up. I have a shrimp/watchman pair, but I started with a hi-fin goby that perished after 3-4 weeks. My pistol shrimp is much, much happier with his watchman buddy. They bonded in less than an hour, and they've been hanging out for a couple months now. Firefish are also good, mostly docile. Just pick one type. I have not had luck this time around when mixing them. A blenny (I love my midas blenny) would be a good addition as well. They are a bit expensive, though still under $100. I have always had ocellaris clowns in my tanks. I personally dream of a pair of maroon clowns, but they are just too aggressive for a community tank of otherwise peaceful fish.
