mag7

I am using a mag 7 to run a sock filter and wanted to know if using a "t" pipe to split the return into 2 differnet pipes affects the return gph? Should I add a ball valve on the bottom of the piping about a foot above the sock filter

your going to run a filter sock off of the ping coming from the pump? usually a filter sock is placed where the overflow runs into the sump.
adding a T will affect gph to the destination because half your water will go one way and half the other way.

no no... I am leting the water go from my overflow into my sock filter through some baffles then back up from a mag7... I am just worried about have the flow down not be equal to the flow back into the tank

the filter sock should not really affect the gph overflowing into the sump. going back to the tank through the returns a T would be ok to split because total gph will be constant.
you should have a ballvalve above the pump to do fine adjustments to flow leaving the pump. your overflow will equalize to whatever is entering the tank, it wont overflow more than you give it.

If the OF box is rated equal or higher than your pump is delivering AFTER your head loss, the flow will always be equal. If you are throttling back your pump so the OF box can keep up, then adding the "T" and diverting the extra flow back through the sump is fine. Put your A BV on the diverted flow side to control the flow through it. This will also determine how much flow goes to the DT. IMO, your best off to pump as much through the DT as the OF box will permit, while still surface skimming. So if you can run it wide open, and still surface skim, then you're all good as it is. Just keep the OF clean and bubble free to prevent a flood.

Just realized you asked about a BV on the drain. IMO, theres no reason to BV the drain. This WILL most likely cause a flood.
