I'm not convinced I have an optimum flow in my tank. The tank is 59x31x17h and contains approx. 145g. I have 3 Tunze 6105 pumps (3000 to 12000l/h) with controller. To get a really good flow across the PSP tank, how would you suggest I place the pumps, and how should I use them (alternating, pulsing, sequence?). Help please..
