Help with Overflow/Water Level flow rate

Hey All,

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.

It does look like they are rated the same. Are you sure of your numbers. Also it`s always slow on the weekends. Be patient someone that knows what`s going on will be by soon.

I also have a Perfecto Cornerflo. It's a 125 with dual overflows, but the overflow should be the same as a 90....they are 1" overflows which can handle 600 gph max. I don't know how your water level can get any higher or lower. The overflow pretty much determines the water level. It can't get lower than the "teeth" of the overflow itself or no water gets to the sump and if it's going over the top of the overflow, you have too much flow and it can't keep up.

For the splashing in the sump, what I did was have my 1" drain line dump into a piece of 3" pvc with a bunch of holes drilled in the bottom. It works great.
