I just bought a house, with a 30,000 gallon in ground pool. The system is a Sta-Rite 3 (dual cartridge) filter system. It also has an Intellichlor Chlorine Generator.
Prior to 2 weeks ago I knew NOTHING about pools, but I have come a long way in just those 2 weeks.
My pool is virtually ready to go now with one pestering issue.
Despite having power washed my 2 cartridges twice now due to them being totally caked with algae, vacuuming twice (to waste in the yard), there is still small amounts of fine dirt that accumulate under each return in the pool. My vinyl liner is kind of old and has some small ripples in it, and this dirt seems to get trapped on these ripples on the pool floor under flow of the return head. No amount of cleaning cartridges or vacuuming to waste seems to stop this ugly fine dirt from making my ripples in the liner look like dark snakes instead.
How long do cartridges last for? And how would I know if I need new ones. $$$$$$$$$ ug.
Thanks for any help!
