Hello all. I'm a new member and have found a lot of help in the forums, but there is one question I can't answer on the internet so far.
I have a 75 gallon tank with a diy 3/4" pvc overflow and a dc pump that I have to set the controller on the lowest setting. I put the pump in a box ( as a baffle ) so that I don't run the sump dry and flood the dt in an overflow failure. This troubled me because for many years the water level in my sump could vary and the overflow keeps the display level, now I have to keep the sump level stationary as well. I am looking into adding a controller to prevent display overflow, but that's a different topic. Which brings me to my point.
The overflow isn't fast enough. I would like to put heaters in the sump and other quality of life improvements. Here's the system: the water flows into the overflow pipe at the surface, travels into the four foot by four inch skimmer (countercurrent, limewood airstone, piston air pump), then to the sump, through a sock and then to the return pump. In the sump is a dual gfo/carbon type reactor. I want to upgrade the overflow to at least one inch and add a weir, but I do not know if the increased flow will negatively affect skimmer performance. Any help would sure be appreciated.
