DWC - small bubbles vs large

[illchemist]

The use of a GH Powergrower without an additional air stone works beautifiully (~3lb/2000W) even with the large bubble produced with the included pump. although I'll probably add an airstone to help things mix more.

Didn't someone say they had best results with a 5" disk?

I have some 4" and they work well but, keep your receipts as they are subject to BLORPage. Some periodically stop emitting small bubbles and then BLORP!
