If you mean SILT, not slit, it could be from a few sources- windblown dust, crumbling concrete or tile grout from the pool, or dirt from a failing filter.

You can use a vacuum to get dead algae off of the bottom of your pool. Once you finish vacuuming, use the pump and filter to remove the particles.

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.

What setting do you turn a hayward sand filer series 200 too when vacuuming?

You have two options when vacuuming a pool. If it a normal weekly vacuume you will set your filter valve to the filter position. This will send the water through the filter and back to the pool. Once your done vacuuming, you then backwash and rinse the filter. A good ratio is 3 min to back wash and 30 seconds to rinse. If your pool is extremely dirty like at the begining of the year, You can sometimes set the filter to the waste position. This will bypass the filter and send the water down the backwash line. This lowers the water in the pool. If your pool is extremely dirty and you try to vacuum with it set to filter, the filter will not catch all the dirt and some will end up back in the pool in the form of dirty or cloudy water. As a pool profesional I always strived for clear water first. You can't clean what you can't see.


Do you need to clean filter at bottom of pool?

There is no filter at the bottom of a pool. Perhaps you are looking at the hydrostatic valve which is there in case your pool is emptied and Will make sure that the pool wont float in ground water.
