Two returns on my 230g each with their own Little Giant. Ones a three and ones a four. I'm now thinking to cut this back to give the skimmer more time as Brad mentioned.
I got a couple of those new Seio pumps and I guess I must have been expecting something more.
However, I probably should have gotten bigger ones.
Oh, and a Mak4 split into two returns on a 67g. That one seems perfect.
