Your return hole size and piping used should be suitable for the pump being used and to not create a restriction..

Typically that would be the same size as the outlet of the pump or greater..

I highly doubt your 4100GPH pump has such a tiny 3/4" outlet..
And NO WAY are you going to get 4100GPH through 3/4" or even 1" really.

oh and FYI.. Typically for a 180G tank having return pump flowrate of up to 1800GPH after head loss.. (typically recommended to have 3 to 10x display tank size) is suitable..
4100GPH is massive overkill unless your sump is in your basement or 10+feet below the display tank
