i have all the materials and inline pump. going with 1inch sch 40. a second mind would be much help. kinda stumped on where i want the pump to sit. i wanna put the return , bio pellot reactor and a uv terilizer on it but placement is beeing a pain in the butt. any1 wanna come over and ponder it with me? the pump is a lil giant 1000 gph. i rebuilt it today, repacked berrings and such. needed badly. now is verry quiet and clean.
