Open Question: I cant get my pool clean. Its 20k inground with cartridge filter.?
I’ve tried about everything. We spoke with a friend who worked for a pool company and he stated that dumping in some earth into the filter may help, but no help at all. We’ve tried vacuuming it but when the water is pushed back into the pool, the algae is still in the water. Its as though the filter isnt catching it. The cartridge is clean, free of gunk. Our filter is Mytilus large cartridge. Shy of contacting a professional cleaning service, I dont know what else to do and help?
We had the water tested and he told us that all of our levels were within the needed range, therefore we didnt need to add any chemicals to the water which was odd b/c our pool is full of algae. We dumped a full container of algaecide in the pool and scrubbed the walls. But after 48 hours of the filter running the pool is still filthy – its as though the filter is not trapping the algae and is pushing it right back into the pool. Is changing from a cartridge filter to a DE filter hard/expensive?
