Not necessarily. With a sump, the position of the overflows determines the water level. Higher/lower return flow just determines the turn over rate of the entire system. The over flows keep the display at a relatively consistent level. Water levels should only change in the sump which is where an ato steps in.With a sump it also has to do with the flow rate. Adjust your return flow so the water level is where you want it. Increase flow for higher and decrease for lower. Then adjust your sump water level.
that sounds about normal. It takes some differences to form the pressure to get the flow sustained.Yeah my flow rate into the tank must be to much because my tank level doesn’t sit at the bottom of the over flow slits like u think it would...the water level is about half way up the slits and draining into the overflow...and then when u look in the drain water column the water level in there is like 4 inches below the tank water level
You might try some kind of cover like egg crate, screen, glass, or combination to contain the splashing. Or even just glass/plastic verticals at the edges.Yes mine is on the bottom of the tank in the corner...and yes mine moves maybe 1/4” depending on flow rate...I was just making sure I wasn’t missing any type of secret way of adjusting this...
My water level is about 3/4-1” from the top of the tank...reason I want it down even further is every day my tank has drips down the front sides of it from these guy playing and splashing at the water surface
