HELP!! my water level in the tank is too high

[Sams0n]

so I have a 200g with a 75g refugium/sump. the water level is right around 1/2' from the top of the tank.. if I add another overflow, will it help lower the water level?

If you shut off the pump how much does the water level drop?

when I shut off the pump water level drops 1/2". it is a custom overflow box with a diy overflow. u think I need to drill more holes into the overflow box for more water to flow into the sump?

well you just need to lower where the water comes in, this determines the height of the water in the tank.

What do u mean where the water comes in? The return? Or where the water goes into the overflow box?

into the over flow box!

Fixed the problem. I drilled more holes lower than the existing holes and the water level is right where I want it. Thanks guys!

Only problem is in a power outage the overflow draining too low and flooding may not be a problem for you depends how full your sump is

great point from Jag. you should do a mock power outage to check your sump capacity.....

Thanks guys! The water fills up about 85% of the tank when the power is out. The water level now is around 1.5" below the top of the tank. And the return is right above the water, so when power goes out, only about 25 gallons flows back down to the sump.
