    What are latest recommendations for new pool as far as chlorination method, filter, etc.

    I haven't had a pool in a few years, but new house and looking to have a pool put in. I am meeting with a pool builder in a few weeks and trying to get ideas and questions ready. I am in the Palm Springs/Rancho Mirage area, so extremely alkaline water with high evaporation rate leads to CH...

    Is there a potion to lower CYA?

    I have a neighbor who is asking me to help him with his pool (spouse volunteered me). He says the pool store told him his CYA was about 180 but they have a potion to lower it. I haven't been to a pool store in a long time, so do they really have a potion to lower CYA. I am thinking it will...

    Target FC for SWG pool in winter when cell not on as much

    In the summer, my pool is in full sun, and my cell is normally set at about 35%. Now that the fall is here and the sun has shifted, my pool is in full shade all day due to a wall immediately south of the pool. Now I am running the cell at 5%. My CYA is at 70, so my target FC for an SWG is 5...

    Will this cause a problem to add to my pool?

    I recently had to have my pool bead blasted and refilled to remove heavy scale above the water line. My CH was 1100 before the pool drain and now is 175. The guy that did the bead blasting gave me 4 bottles of this product, All-Clear Stain & Scale, and he said to put a bottle in every three...

    CYA level recommended for Salt Water Pool in Palm Springs, CA

    I just purchased a house that has a pool and haven't any experience other than what I have been reading here. I read in the Water Balance for SWGs topic in the pool school that CYA level should be kept at 70 - 80 and mine is about 35. When I went to the local Leslies to purchase the CYA to...
