HI Guys

I have a 490/500L display tank and a 90L odd sump,

My curent return pump spec's indicate about 750L an hour return ..... is this sufficient? or should i be looking at a much higher rate?

cheers

well im running a 350L display and have a 8000l/h return pump. its pretty high but it creates some nice flow in my tank. I think 750l/h is to slow in my opinion

the pump i have is specked at 3500L an hour, but with the head to contend with I estimate it to be at 750L an hour ..... is your return an effective 1800lh or is that the pump spec at 0m head???

on my 2500L (total system volume) i will be running a smallish pump that will give me +- 6000l/h at 2M head high. my sump is 600wide so i will have a slow gentle flow over the DSB and the cheato. in the tank there will be a 12000l/h CLS and 2 or 3 palorios when they come out.

So far i have one M820 and one no name brand powerhead in the DT, but that will be upgraded this weekend ....
