Hi All -
I need some help from you wise gurus (or wise guys
On my 55g freshwater tank I have set up an Eheim 1250 pump feeding a chiller. The water is drawn from the tank via a homebrew intake tube, runs down through the pump, chiller, and then back to a spraybar into the tank.
The problem I'm having is air bubbles in the line. I think the problem is in the u-tube coming over the tank on the input side. I have read that I can drill a hole in the top of U and silicone a one-way air check valve to let the trapped air out. Does that work? Alternatively, I also read that some have hooked airline tubing from the top of the "u" to the venturi input on a powerhead. Would that work better?
