overflow question

[Pazil]

I agree what what the others have said in regards to the amount of flow through the sump being important..... However if the sump is designed properly for a higher flow you will not get micro bubbles and the a good skimmer should still work effectively. I run a Dart return on full throttle... which means I am putting approx. 3000 gph @ 4' of head loss(20x turn over)through my sump and have no micro bubbles and have to empty my skimmer cup every 2 days. I run no powerheads and only have the return pump and a Tunze nano wavemaker for internal flow. There are no dead spots in the tank and no settlement of debris.

Cheers
