    Anything but gyre, what trash

    in General Discussion

    Interesting... I have been thinking about getting some. The youtube vid I found said they were almost silent as long as you weren't trying to drive them close to their max which arguably one shouldn't be doing anyway. Icecap licensed the design, but I don't know who actually makes them. I thought that tucking them up against the top of the tank would provide more viewing area and be less noticeable than something in the middle of the side panels of the tank, not to mention the MP-40s seem to like to slide down all the time even at the strongest alignment of the magnet.  That doesn't sound like it matches your experience. What size is your tank?

    Solar Sea Slugs: my new project

    in Conservation & Sustainability

    Very interesting. Thanks for posting!

     

    About how much shaving brush do they go through? Are you rotating them out like starfish for harlequin shrimp or just getting new ones?

     

    What happens if you reverse your experiment and try maintaining them with a good food source but low light levels? If photosynthesis isn't contributing to their energy levels then they may not have any dependency at all.

     

    I wonder if you could come up with an extracted version of the chloroplasts that they would consume and if it would be possible to dye it to see if they are swapping them out and at what rate.

    Jawfish cut on side of head

    in General Discussion

    My jaw fish would hide every couple months. Sometimes for a week or two at a time. I dug them out a couple times but with one exception where one got trapped inside a piece of PVC they were always fine. Just let him be and feed him again when he comes out.

    Help needed to bend rigid conduit for light hanger

    in General Discussion

    Bending is not the only option, you can also just buy fittings readily avaliable at Home Depot to throw a few 90 degree angles on there, and use metal PVC pipe painted black. Check out Brad908's old build.

    That looks like it would work, but I'd rather avoid piecing it together with 2' sections which means I will need to get the pipes cut and threaded. I've seen the threading machine at HD. Does anyone have experience trying to get them to cut and thread? 

     

    i have a heavy duty hydraulic pipe bender that you can come use anytime.  i live in fairfax station.  just let me know if you are interested.

    Thanks

     

    I used the fittings too and painted it black. I think it looks better than a bent pipe.

    Did you build yours out of short sections like Brad908?

     

    I would go the 3/4 emt handbender route...the less fittings and the better....and prefab bends usually are a bit more expensive.

     

     

    Where in Arlington are you at? I might be working near you and could help out if I am.

    I'm in Clarendon. Do you work with conduit?

    Heaters in overflow?

    in General Discussion

    The heater loses power in an outage, but it stays hot for a good while. Depending on the timing of things, it could still break if the water restarts and pours over the now hot glass. You could just set your overflow so it stays full in the event of an outage.

    Unfortunately, you'd have to dissect the starfish to tell if it is a boy or girl. They don't like that much.

     

    Yes. There are many species of starfish that are poisonous and even deadly to humans. The crown of thorns, the sun star, the spiny sun star and the leather star are some of them. Their spines are the poisonous parts.
     

    A sea star's  lifespan ranges from 5-35 years.

     

    An anemone is a member of a group of animals called Cnidaria. These animals live a verrry long time. They don't have physical markers like rings on a tree so it can be hard to tell. Some people think they can go on living forever if nothing comes along to eat them.

     

     

    Although starfish do not have many well-defined sense organs, they are sensitive to touch, light, temperature, orientation and the status of the water around them. The tube feet, especially those at the tips of the rays, are also sensitive to chemicals, enabling the starfish to detect odour sources such as food. There are eyespots at the ends of the arms.
    While a starfish lacks a centralized brain, it has a complex nervous system running along each arm. The starfish does not have the capacity to plan its actions. If one arm detects an attractive odour, it becomes dominant and temporarily over-rides the other arms to initiate movement towards the prey. The mechanism for this is not fully understood.

     

     
    A sea star pulls food to teh center of it's body where it's mouth is. Here is an interesting video of one eating: http://www.youtube.com/watch?v=A100m5EpfFI

     

    DIY LED Fuge Light

    in Do It Yourself

    I used some that look the same on mine and they did well while they worked. I got them from dx.com though instead of ebay. The drivers also look better here with heatsinks. My drivers burnt out after a couple months, but I didn't enclose them which may be the reason. The LEDs put out a LOT of heat. Make sure you check the heatsink to see that the GPU cooler is keeping up before you strap it below your stand.

    Max Sump for 72 g bowfront

    in General Discussion

    So you were actually able to get the 20L in without cutting or modifying the stand?

    Yes, but only from the back. The opening in the back was larger than the front and there was no center brace. Tipped it up and it would go in.

     

     

    Not sure if I'm understanding what you mean about the water level, why should it matter what the water level is? If the pump is too fast even if the sump were 30" tall it would eventually empty the return chamber wouldn't it? If my baffles are set up with enough height to keep the pump submerged, I should be able to control the amount of water in that chamber with my ATO.

    Pour a gallon of water in a bowl and then pour another gallon of water in a kids swimming pool. Which is deeper? Same thing smaller scale. The pump needs a certain minimum depth to be able to suck water into itself.  I didn't have baffles in my sump and it may very well not be an issue for you anyway. At that time I was running 1/3 - 1/2 of my turnover through the sump.

    Max Sump for 72 g bowfront

    in General Discussion

    I ended up using a 20H under mine. The 20 long was too hard to get in and out for cleaning. Also, depending on the speed of your return pump, the water level may drop so fast that the pump will run dry before the overflow fills up. The taller tank helps keep the depth of water sufficient  to let it start refilling before it hits the bottom. May not apply, but it happened to me.

    Need to move tank 5 feet

    in General Discussion

    Short pieces of PVC work well to roll the thank as well. Use three pieces so you always have two under it or it will teeter when is goes past the center... I drained my 180 and had my SO help me lift the edge of the stand and then rolled the first piece under with my foot. Happy to help too if you are close by.

    Chameleon Mandarin

    in General Discussion

    It's a little unnerving. The first time we saw one of our mandarins do it we thought it was dead. Most all of our other fish change at night, but the mandarins in particular look startlingly different.
