That tank is sweet! Ever since I upgraded to MH, I've been slowly converting my 50 gal to SPS/Clam. . .

She quickly acclimated them to her reef tank and then left for MACNA.
The problem with the checkvalve was that the gravel substrate was constantly drawn in to the return line each time the pump turned off, because the tank would automatically try to drain. The vacuum of this event drew in the gravel, and thus the valve could not seal.
The concept is great as long as the pump is running non-stop. The checkvalve is the flaw, but I still can't come up with an alternative solution.
I love the pictures in this thread, and the tank looks excellent. I'd make one myself if I could figure out a solution. The only one I can come up with is a tower in the center that breaks the surface unfortunately.
melev said:Cheri, I just woke up so forgive my lack of comprehension (I'm drinking coffee, I promise!), but how does that solve the problem?
Water comes up the standpipe, comes out the holes, goes down the inverted 'vase' and flows into the tank. When the pump is off, water siphons out the same way, right? What breaks the siphon?
melev said:Ah. I really wish there was a more elegant solution for this situation, because I'd make one myself. I guess a black acrylic tower in the center could house the anti-siphon solution, merely to hide it. Or to make something on the end to house and hide it, but it would steal one edge or at least ruin the simple symmetry.
