Water turn over

Recommended Posts

Is too much too much?

New tank is sumped wet/dry (approx300L total) turnover from pump is around x10,

Will b heavly stocked, will moving water thru sump that fast give time for bacteria to do there thing? Or change to a slower pump?..

It will all depend on how big each section in your sump is,the smaller the section the faster the water will flow past the media and the bigger the section will allow more time for bacteria to do there thing.it will be trial and error to find out what works regarding the turn over rate all depending on how much you feed them.

Given its a sump....it will be under the tank?

the pump turn over will be less because it has to pump the water 1metre or so vertically

Check manufacturers data it should tell you how much turn over you lose due to "Head loss"

ps You are correct you get better efficiency with biological filtration @ slower flow rates....that is why air driven sponge filters do such a good job. I'd suggest if sump is Wet/Dry it will most likely be over-kill.....biggest issue will be pump or power failure
