It looks as the main drive pump on my 40 breeder is on its last legs. I bought it used, and when I looked up the info on it, it says the max was 400 gph. and I am sure it had at least 3 feet of head pressure getting up to the main tank. Since I have to replace it, I am hoping for some good suggestions at to what to replace it with. the tank is a 40 breeder. with a bit of SPS and palys and zoa's. I run a wp25 on its lowest setting on wave 1 and am pretty happy with the current. Oolithic mixed with crushed coral substrate as the bed. any help here would be hot. there are a lot of choices out there. thanks for your time. Brad
