Removed mesh winter cover, and pool is very green and dirty! Could barely see to bottom in 3' shallow end, no chance of seeing the bottom in the deep end! Starting first SLAM process, checked pH first and got it in range. Want to confirm, I should stick with only chlorine and not use any algaecide? Also, any issues with using dichlor to start? CYA is not registering, so want to get CYA level up. Will track carefully and switch to liquid chlorine when CYA gets to around 30. Thanks for the feedback!
