your problem has to do with your filter.if your filter is DE you have a hole in your grids or manifold is cracked if it is a sand filter you either have a craced lateral or the filter is in neeb of backwasing .in case of brken lateral you will also see sand in pool as for cartridge check for damaged pleats .sand filters are alos known to to wear spider gaskeks in the rotation valve

Your filter needs maintenance. You are probably using a sand filter.

You either need to clean the sand (with a special cleaner such as sulfamic acid) and top up the level, or you need to replace all the sand. An inspection of the sand will indicate your course of action.

I got some zeolite from a shop that was closing down and it has really done wonders for my pool water. We have problems with hardness here and my filter sand solidified. No problems since then.

That's a classic sand filter in need of attention. Maintaining a sand filter is real simple. You need a couple of hours in the spring and you're all set for the year after that.
