so i finally got my sump up and running. i have a cpr50 overflow box, and attached to it i have a small powerhead(800 rena or somwthing) which draws the air out of the box to create a syphion. but for some reason i keep getting air bubbles in the box which is causing the powerhead to blow micro air bubble into the tank. now my question is does it take time for the overflow box to stop drawing in air. or is my box not air tight (haha)?? should i try to slow down the pumps so it doesnt draw out all the air in the box? i dont want these bubbles in my tank looks like crap and i cant add coral till its fixed. HELP!!
