you need to test your pump rate at the DTOh I got that done already. My question is are there any tricks to dialing it back to just the right rate so it matches The overflow. Or is it just fiddling with it till its set
use a pint bottle or jug and time how long it takes to fill.Note this down
you have a 300gph overflow
300/60=5 gallons / min
5x8=40pints/min
60/40=1.5 pints/min
so you need to set your pump up at 1.5 pints per minute max,try to keep the pump set to about 1.3 pints /min
I hope this helps
