Do you mean leaf skimmers net that are attached to the pole? If so, Yes. The aluminum outer support ring just under the plastic wear sleeve will leave a gray to black line as you push it along the bottom of the pool. If the plastic cap or wear sleeve is worn on the outer edges, down to the aluminum that too is where the marks are coming from. If you are using the skimmer with the net inverted that too exposes the aluminum support bar.

What valves do you leave open when cleaning pool?
You should have two valves: one for the skimmers and another for the bottom drain. Close the valve to the bottom drain. One of your skimmers should have a rotating disc which will cover the intake at the bottom of the skimmer intake hole. Rotate the disc. In this manner all the suction from the pool pump will be at the one remaining skimmer. Attach your cleaning hose to this remaining skimmer while vacuuming the pool.

How do you vacuum the waste in your below ground swimming pool?
Your question seems too easy as it is a basic requirement of pool cleaning. However: Attach your vacuum head to your side outlet (unscrew the cover in the side of the pool) using a floating hose. turn off the valves to the bottom drain and the skimmers, leave the pump setting on filtration, fill the hose with water and turn on the pump. After vacuuming the bottom of the pool, switch off pump and return valves to previous setting. be sure to backwash the filter after cleaning if required.
