Massive sub pumps or cut into return line for skimmer?

[Hustler]

I will get a pic up asap,
The way its set up i have the skimmer draining into the bulkhead on the left where my overflow dump and my return inline taking it from far right
Myka, I bought 2 pumps 1 to replace my spa pump and the other for the skimmer
as of right now im running the 3800gpg as my return and its still overkill as far as sump flow over the baffles and i still have the 5800gph just sitting here plus my old spa pump so i should be covered for a back up either way
My rona was out of 1 1/2" Ts (always something) so im hooped till monday unless i find them elsewhere but this is the plan im sticking with LOL
