How to run seaswirl with RR overflow?

[james1990]

I'm considering using two sea swirls in my 150tall upgrade to limit the use of vortechs. I never used them but they seem rock solid and less maintenance and alot less noise.

The biggest benefit is the peace of mind with anemones.

My question: I have dual overflows and a 3/4th hole in each for the return. The seaswirls need the return to run over the top of the tank. Should I use the return bulkheads as 2 more drains? Plug them?

turn both holes in the overflow into drains and put the sea swirls on the side like normal

I haven't seen any setups running 4 drains I'm not sure how that would work out
