I did some searching around and trying to find acrylic. And its a bit more exspensive then I have hoped for. I was going to use 3/8" thick acrylic. How thin can I go. I am making a small tank. Only 7.7 gallons. Could I get away with just using the stuff I can get at home depot, So far just for the acrylic and lights it would be almost 200. I wasnt planing on spending that much. Any thoughts?

Did you know that various types of corals when attached to the skull with woodscrews can make an ordinary child appear just like a deer?

srgtkoons,

I think 3/8 will suffice. My refugium is 25 gallons and it is made out of 1/4". It bows slightly, I do not think that 7 gallons will bow 3/8".

Sorry i explained that poorly. I want to use thiner then 3/8. There is stuff at home depot that is pretty thin. But with how small a tank im doing i dont think it should be that much of a problem. Any other ideas? I was going to build the hood for it and have the hood add some support to it.

sgt:

You should use 1/4".

I just made a sump that is 29x15x17 (about 29 gal) using 1/4". For 7 gal, 1/4 would be the best choice. I think the thinner acrylic is too flexible to work.
