How to lower sump water level?

[Evieeeeee]

So my sump's water level is staying above the baffles and I'm wondering how to lower it to be in line with the baffles. I plumbed in a filter roller expecting it to be at the right height and the increased water height is making it constantly roll as it triggers the float. I was thinking of getting a saw like this

and cutting the return section weir to be wider/deeper? Would this help lower the water level to the baffle height? Any other suggestions? Thanks!

Have you a dc return, increasing that is one way.

Can you take a father back picture so i can see what your trying to explain to me?

Increase the output of return pump or decrease the amount of water running to the sump

I've tried increasing the speed and also tried decreasing it to as low as possible and the water level seems fairly consistent and only change in the return chamber.

I agree with a few above with reducing the incoming flow, and/or increasing the outbound flow. Is this a drilled tank? Do you have an overflow box? You can adjust the height of that and a super super simple way is just to remove a little water. Every once in a while I overfill a little and then just take a couple gallons out. Our return pump is likely aging because we used to use 2 overflow tubes and now we only use one or our pump won’t keep up.

have you left a good few minutes between each change? The change doesn't happen straight away.

If you remove some water the level will drop in the section with the return pump but depending on the flow rate it is hard to say how much it will lower the level in the rest of the sump. You'll have to test it yourself.

Yeah been going at it for an hour now just changing settings.

Drilled tank, herbie overflow. I'm using a neptune COR and setting it between the various speeds to test and these pictures are at 100% speed

In either case it changes nothing. Other than a scenario where the drain is too small for the return pump(and you flood the DT) the return flow always matches the drain to sump flow. Make it 20000gph or 20gph the flow in each direction will be equal. It wont change the water height in the DT or sump.

Remove about 5 gallons of water (turn off ATO first) and then try adjusting flow, but rn there is too much water.

The water was added recently after going to 100% because it was sucking air. The water level in the first two chambers was still the same point before I added more water. This is why I suspected that the weir was restricting flow since the last chamber would go up and down but the first two wouldn't move much at all

looking at the picture it seems like there is around 1 inch of room for the water level to drop but its hard to tell for sure by the pic and they are very narrow channels so it doesn't take much flow to get what your seeing. I am personally of the belief that it is best to have around 5x or lower return rate which is probably much less than 100÷ for that pump. The issue is that regardless of what you do if it is sucking air your not going to be able to drop the baffle down very much. Lower return rate will help with the sucking ad well. If it is still not enough you can try drilling around the bottom of the slits.

Too full. Your water level line is level all across the sump in the pic you gave i asked for. Like others said. Take some out. The final return section where your return pump will be the water level chamber. This chamber will go up and down as the fresh water evaps.
Ato. Draw a water line. Or a piece of tape will help you keep track of this

It was only sucking because I raised the speed to 100% and everytime I raise the speed it lowers the water level from the return chamber. There's plenty of room to take water out and not suck air at 100% I just added more than was necessary since my ATO isn't on yet and I'm just fill testing

I thought I made it pretty clear that the water was added AFTER the water level issue was found because of air sucking but here you go. Return chamber is lower and the water level doesn't change in the first two chambers. It's not due to lower too much water

U have it set up backwords? The return should be on the other end? Lol. My guess.

Ive also had a sump where i did the return in the middle and just T'd off the main return to a fuge dsb that overflowed back into the return section.
Its hard to tell not being their sorry.

That picture is much more useful(to be honest it was not clear before at least for me). Yes looks like you need to cut down that wier.
