Pray for a salt water system
Sand filters are not cleaned with chemicals . they are back washed when required. every four or five years it pays to replace the sand in a sand filter to maintain its efficiency.
Nothing if its a sand filter However if sand is coming into the pool from the filter then you may have to replace one ore more laterals in the sand filter as they have worn and are letting sand through to the pool,
If you have a sand filter the laterals in it may be starting to show signs of wear these wil blow sand from the sand filter into the pool when they wear out.
It could damage the internal PVC of the filter and cause sand to get in your pool.
The sand filter wont make a pool green this happens a s a result of algae.
If you do not see your water level going down on above ground pools they use sand for the bottom. My first guess would be that if you have a sand filter that the sand is coming from the filter just a bad or faulty gasket I do not know if you change the sand in your filter or you have someone do it, just have the person vacuum the sand up with the pool vacuum. have someone open the filter up and look at the gasket. A thin coat of sand? Well if is all over the bottom of the pool it is either a fine sediment that the filter cannot pick up or DE. If you have a DE filter and it is DE on the bottom of the pool you either have a problem with the internal components or, if you have a multiport valve, you may have a problem with that. What ever you have the best way to get rid of it is to vacuum it to waste. If you have a multiport valve you should have a setting marked waste and you would vacuum the pool while the valve was in this position. This bypasses the filer and run the water out the backwash line. Any other filter configuration I would have to know what type of configuration you have to advise you on how best to deal with this issue. If this "sand" is all in one spot by the return jet then you probably have a broke lateral at the bottom of the filer. You will need to replace the lateral and if the laterals are over 6 years old replace all of them.
If you are getting sand coming into the pool and have a sand filter you may have to replace worn laterals in the sand filter.
No, it'll blow right back to the pool which will then make it hard to remove. Sand filters REQUIRE a #20 grid pool filter sand. There is also another product possible called zeolite for sand filters... it will filter finer than sand.
Take the mutiport controls of the top of the unit. This will allow you to see inside where the sand is. The easiest way to remove the sand is to get a venturi pump these go on the end of the garden hose and use the taps water to suck the sand out of the filer housing. (ask your pool shop about this device) Once the filter is empty replace the sand with whatever you want to throw in there. Screw the multiport back on and you are done
Yes, it just depends on what kind of sand it is
Your filter will tell you on the side of it how much media sand to put in it.
