The goal for a fowlr
system is to have around 10-20x turnover, compared to reef tanks maxing out around 50x. So, with a 29 gallon, you will want between 290-580 gph
. This can be done through multiple powerheads to give a more randomized flow pattern to help assist with little to no 'dead zones'.
In terms of feeding, I feed my reef tank every other day. I prefer frozen foods.
