i have a big area in my "fish room" (with only two tanks)
i checked on the tank calculator , and i have enough room to
build a 350 gal
what is the best transparent material/glass for the front of the tank, and stocking ideas
I'm not personally a diy person but I believe you can build a 3/4" plywood tank that you seal and line with pondliner then add an acrylic or glass viewing panel.
Glass or acrylic depending on preference and price or how you decide to seal the wood.
The size depends on the tank dimensions and height.
There are many thread on plywood builds.
