i've been toying with the idea of drilling the back 2 sides and maybe making it a cl. what do you think? cl with a sequence dart on it?!?! that'll gove me somewhere in the neighborhood of 90x turnover.
I won't need a chiller. I keep the house at 70 - 72 degrees all year and I left a large part of the back of the canopy open.
I am going to have approx. 120x turnover once I get my new powerheads. Bare bottom tanks need a lot of flow...
