Last summer we did not open our pool. We had particularly funky water as a result. We needed to paint our pool this season, which we did, so all is good. While ordering a new pump basket from my old pool supply store, and discussing not opening the pool last summer, the manager suggested I use a sand filter cleaner. She said the sand filter probably had lots of 'gunk' in it due to it sitting idle last summer.
Is it a good idea to use this? The directions say to pour 8 oz. in the skimmer while the filter is backwashing and use each time I backwash.
