Well I broke down and bought a stand/canopy for Brooke's nemo tank. I was going to build it, but it just wasn't happening. I had to replace the 20g sump for a 15g tall to accommodate the stand. I want to install baffles to minimize bubbles in the display tank. I also want to use it as a fuge with chaeto. So I want to know the best way to proceed ie what material to use for baffles and configuration ect. Anyone have suggestions?
