Excellent..thanks a lot guys. Those were the answers that I was looking for. Danny, the overflow I have is a lifereef hangon rated at 700 gph and I am going to buy a rio 14HF for the return pump. It puts out about 640 gph at 4' head. The overflow comes with a 1" drain so how would I attach a larger diameter piece of pvc..say 1.25" to a 1" drain? I take there are adapters? Also is it necessary to go to a larger drain because I thought that the overflow would match the output of the return pump and that a larger drain could also be noisier. If it is necessary would it be easier to make the return line 1" pipe instead of 3/4"or does it have to be the drain that needs to be the larger diameter pvc?
