So i upgraded to a 240 from a 100 gallon.. Here is a pic im running a QuietOne 9000 pump return with a 60 gallon sump with only 1 return but thinking of adding 1 more return so that i can have 2 1 1/2 " overflows back to the sump. also supplemented by a 405 . Let me know what you think and any helpful ideas! thanks!
