I've got my DIY LED fixture up on my 29g tank and everything is getting settled. I'd really like to get some pencilfish but from what I've heard they like to carpet-dive.
Requirements for my "cover"
1) Prevent fish from jumping out
2) Not significantly reduce the amount of light coming into the tank.
3) Be easily removed (or opened) to allow for easy feeding, water changes, and maintenance
4) Modifiable to fit the canister filter inlet/outlet, wires, and DIY c02.
5) Fit within/under my light fixture
Here's a look at the tank from a couple of weeks ago to get an idea of what I have set up for the light canopy.
Some solutions I've thought of are as follows and I'd like to hear your stories and opinions.
1) Egg Crate/Light Diffuser - This stuff is pretty inexpensive but I don't want to be cutting down on the light too much into the tank. Plus, I'd rather not see it protruding out from the top of the tank.
2) Acrylic Sheeting - cut to size. This will be a bit more expensive but it will be hidden by the trim. I used acrylic sheeting on my 55g which worked out well but the pannels on that would be smaller. I'd probably have to go with around .25" thick acrylic to prevent a lot of warping. It will help cut down on the amount of evaporation from the tank.
3) Wire Top (Reptile Top) - This seems like an easy commercial product to cover the tank. It may be trickier to cut the openings for the filter inserts, especially still allowing the top to be removed.
Does anyone have any suggestions?
