My frag tank is 6ft long and I have a MH
pendent on one side that covers a 2x2 area and a 2x96 PC
DIY fixture for the other 4x2 section.
On the chemical warfare issue, I have a little rubbermaid box that the frag tank drains into that I keep a bag of carbon and some sponge in. The water drain from it into the sump via holes I drilled.
Congrats on the frag tank. I started with a 10gal, then I had a 20L, then a 33L and now I have a 72x24x13 frag tank.
