I am using an aqua excel controller on my 160 gallon Red Sea max. How do I find the balance between the flow rate and the valve control to quiet the down flow. It is so loud. I am a relative newbie and I bought the set up used
I'm not familiar with that controller but the procedure is the same regardless. I don't really try to balance it between the pump and valve. I just decide how much flow I want from the return and set that then use the valve. I don't try to set the overflow water level with the pump controller. The jebao return pumps on my redsea tanks I run around 60% then use the valve to adjust the level so there is just a trickle going down the e drain.
