If you have a skimmer, let it overflow back into the sump. That way you still have the aeration, but you won't skim out the Prazi.thanks! Will dose when it arrives tomorrow.
I have an air stone in my sump, will add 2 more into the display also to increase aeration. Appreciate your advice and input!!
If you have good surface flow and a sump, I wouldn't think you will need airstones in the display.
