i have a little giant that will do 1200 gallons. its fan cooled. excepts 1" inlet/outlet. its too big for my return. think im going to get a mak 3 or an iwaki 40rlt. it'll let it go for 75 bucks. its in good condition. just don't wanna have to listen to my overflow fart as the pump max's my 1" drain. LMK fast cause i'll order a new pump if your down.

cheers,

kurt
