Adjusting the water level for the sump

[le9569]

Hello,
I just created a sump. My tank doesn't have a built-in overflow. Now I have to control the water out and in the tank so that there is constant in water change. It is so tough for me to do so.

I do have a valve for water out and another one for water in. The valves are so hard to turn to make

Is there a trick, a better way to do?

Thanks.

Not sure I understand the issue, Do you have any pics or diagrams you can show us.

Are you using a Hang on Overflow? What is your return pump?

The water from the tank should just flow unrestricted to the sump and the return pump will pump it back up.

I'm not sure if I understand either, but how a sump works (however it is plumbed in to the tank) whatever is pumped into the tank (meaning gph of flow) will be returned to the sump at the same rate. The only thing that will hinder this from working properly is if the pump is too strong for the overflow or whatever you are using to return water to the sump can handle. So if you are draining your sump quicker than you can put the water back into the tank, you need to either upgrade your return plumbing size, get a smaller pump or put a valve on the output of the return pump and back off the flow some until it balances out. That is why you will see overflows have a maximum flow rate. Their design in bulkhead/plumbing size and quantity etc. will determine how much it can handle. Not sure if that answered your question any, but pics will definately help us understand what you are trying to accomplish

I hope your not using a powerhead to move water from your tank to your sump. ??

This is what it sounds like to me too.

You will never be able to match the outputs of two seperate pumps. You will either end up draining the sump (overflowing the tank) or draining the tank (overflowing the sump).

If this is indeed what you are trying to do, stop immediatly! Check out the DIY section here. Search for overflows and sumps. There is tons of information here on that stuff. Also, you don't need a "built-in" overflow to have an overflow.

Finn & Meche, I think you 2 might of hit it on the head here.

ya, not recomended use 2 power heads to move and return water. (aka "flood")

get your self a over flow from CRP and then all you need is a big pump, (to match your overflow) and you wont have any problems
