HOW MUCH CURRENT? HOW should I direct my returns?
I don't know if my plants should be blowing around like corals in a reef tank or there should only be a very slight one.
Do people put additional power heads in thier plant tanks? It seems like most people just use a canister filter, IMO they are not very strong current makers.
My tank is a 200 gallon and I have an Iwaki 70 rlt with 4 returns.
Where would you guys point them?
