Gyre or chaos...that is the question.
I have my flow currently setup as a gyre as shown in the pic below. I'm using 3 MP40WQDs and 2 Maxspect Gyre 150s. As I went to replace one of my MP40s (cuz the motor got really loud...and I couldn't stand the noise), I set it up temporarily such that I caused less of a gyre and perhaps more chaotic flow. As a result, it seemed that there was much more movement in the tank. Anyway, I now wonder if I'm better off just setting up the powerheads without worrying if I have a gyre or not? Besides, the Maxspects are too noisy for me. So, I would like to pull those out.
Thoughts?
