Pool closing

[Aimbdd]

So we just had a super mesh safety cover installed, and I know were supposed to keep the water level below the tile. Is there any negatives to leaving a plastic pump sit on the pool steps, submerged, and run it as needed to keep the water level low?
Also, since I’m pumping water out, do I need to check csi, and how would I go about adjusting any parameter that’s out of limits without a main pump? Thank you in advance.

Leaving a submersible pump in the pool can create rust stains. Cheap submersible pumps are not designed for continuous submerged applications. They are design as point of use water removal devices. The cheap ones often have externally exposed metal screens that are not high quality stainless steel. These pumps are not designed for moving water over long periods of time and pool water can easily become corrosive towards metals when chlorine and chloride are present.

No.
