Just wanted everyone's thoughts on using a valve to turn down the output of a pump. I have done it before on smaller reactor pumps and have never had any issues but I wanted everyone's thoughts on doing this with larger pumps like return pumps.
What is the point that valving it down too much will hurt the pump in the long term. (ie. turning it down 25% does do much but 50% will decrease the life of the pump a lot)
I have a mag 7 on my 90 gal for a return pump that I run full open but some people have said that I could valve it down to increase contact time in the sump for the skimmer.
I have an avast cs1 pegleg that I just finished buidling (love it btw)
