PLEASE DEFINE WHAT YOU ARE CALLING THE "POOL FILTER"! The filter (large tank) can not run fast or slow. So what do you mean? Are you talking about the motor on the pump? Then, what does it sound like or what noise does it make or not make? Can not make an informed answer until I have all the facts.

Salt is not a filter, it is added to pool water to allow a chlorine generator to operate.
How do you back flush a pool filter?
Plugged pump, very dirty filter. Do you actually mean the filter or the pump. Filter is big tank. Pump is small unit with motor attached.
Most likely it is caused by an air leak somewhere in the system allowing the filter to drain back to the pool through the suction lines. You will probably see DE in the pump pot as well.
The filter needs to be dismantled to find the damaged elements and replace them. While the filter is down have all the grids inspected and cleaned to determine if more are damaged. Depending upon filter brand there are 8 grids.
The cleaning schedules varies from filter to filter, but a general guideline on any swimming pool filter is to take a reading when the filter is clean, then clean the pool filter when the pressure rises about 10 psi.
From the pool
Long enough to clean the pool.
A pool skimmer is generally built into the side of or around the top of a swimming pool in order to skim debris from the surface of the water. A pool filter is built into the plumbing in order to filter fine debris from the water itself.
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 don't have to change the pool filter for years Unless it gets damaged. You do however have to clean the pool filter whenever the presure leading to the filter gets too high. This indicates a dirty filter that is not allowing water to get through effectively.
