is anybody useing a water blaster 10000 for a return pump. I just recived mine to replace 2 rio hyperflow 20 witch are rated at 1290 gph, so i figured a 2600 gph pump to replace. my tank is a 210 reef, and from what i have been reading on here is that a few people only used the 7000. I could build a manifold and run my calcium reactor, gfo reactor and uv filter also have a valve to slow down flow if i have to ? any sugestions?
