I have a 90g Marineland Corner overflow tank. It has a 1" Drain/bulkhead, but the overflow tube is 1.5" and gets reduced as it goes into the bulkhead.
I recently upgreaded my sump from a Pro Clear Aquatics 125 Wet/Dry Sump to a custom built 34x15x15 Sump/Refugium.
I don't know that the sump makes any difference at all!? I also upgreaded my pump from a RIO 2100 (375gph @ 4' Head) to a Pan World 50PX-X (Aprox 720gph @ 4' Head).
The Rio 2100 had 3/4" Outlet and the PanWorld has 1" outlet. Don't know if that makes any difference? Just trying to give all possible information.
The problem I have is that I have to valve the pump back about 50% or it over powers the overflow and gurgles in the dump of the sump, which spashes all over. According to Marineland the overflow is rated for 700 GPH
. So I should be able to have the pump running at almost full flow!
Also I have noticed that the water level in the tank is about 1/2" lower than it was with the old setup and the flow out of the discharge coming back into the tank seems to be considerably less than before. I have no way to test the flow other than by looks.
I would like to be able to open up my pump a bit more and get more flow into the tank, but it seems the overflow itself is maxed out.
Anyone have any input/info/suggestions?
Thanks in advance.
