I have had algae in the pool for almost a week now. I have tried yellow out after raising the ph, but it is still there. Last night, raised the ph because it lowered again, scrubbed the sides and bottom of the pool. I have put in a gallon of bleach this morning and checked it an hour later and no movement on the FC. I then added shock to the pool and still no movement.
Any suggestions, before my husband drains the entire pool? By the way we have a 21' round pool.
