I am upgrading my return pump to the DC Diable 5500 return pump. It will be replacing the OR 3500 that is on the tank right now, the new pump will give me added flow from the returns. I hope this allows me to reduce the number of power heads in the tank.
Ok its been a while since I have updated this thread, the tank is doing great and the rockwork has been revamped several times, will get some new pics up.
