thanks for prompt reply. So you are recommending up2000/l over up3000? I just tried eheim 1260 and got a very nice flow (a bit strong but ok), however the water temp rised by 1-1.5C. I dont intend to use chiller so I need to look for another lower wattage pump that will give a decent flow. Aside from aquabee, do you have other punp to recommend?
It's nice to hear that it would work. As long as there is decent flow, I am ok as I will install wavemaker to add to the water movement in the main.
