I have an acrylic 100 gallon. On the top of it, it has two 1.25" holes that I am going to use for the in/out tubes to my sump.
Question is should I use 1/2" or 3/4" PVC
to the sump? Will it be that big of a difference in GPH
flow. I think I am just going to use a 3/4" (bigger the better) and attach a valve before the pump to control the flow rate.
Is this the best way to do it?
