Thanks Kurt,
Unforutnally I lost ALL three clams. No idea why. Like I mentioned I started using phosban again after I set the tank up... one clam started to look like it had pinched mantel and died the day after I noticed that. I stoped using phosban and did a 30gallon water change. One month later the ohter two clams had the same fate, I'm suspecting maybe a nusance critter since they were all on the bottom of the tank near each other. Or some contagious condition I'm unaware of.
The canopy was purchased, and I had the metal rails installed for the lights to rest on.
Thanks guys, I'll try to get an "updated" picture. I've been traveling for work alot and its by no means a "show" tank.
