    Walls appear darker than floor, not sure the cause

    I have been using the Pool Math app for three years ever since I got my pool and am very anal about my water chemistry but lately I am wondering if there is an issue. Since last year I have noticed that my walls appear darker than the floor of the pool. I have always chalked it up to shadowing...

    Just did a refill, balance is way off. Need help!

    Need a bit of help here. Had the pool drained for an acid wash and refilled it but balance is now way off. A number of issues: PH is extremely low to the point that my test kit said I needed 13 drops to get to my target. FC is basically 0 TA does not even get to the point where the water...

    Acid Wash scheduled

    My pool was finished in September and we have not been happy with the finish (splotchy).

    Iron staining product recommendation?

    Black spores/ash on surface of pool water

    I have noticed what I thought was black ash on the surface of my pool. I thought it was ash because it occurred the day after we had a major windstorm and I had left our fire pit uncovered. My assumption was that ash had been blown into the pool. However it has been 3 or 4 weeks and I continue...

    Out of control PH

    My gunite pool was completed in late September and I have been maintaining my water chemistry using the Pool Math app (great tool by the way!). I have been able to keep everything fairly stable except for PH. It continually runs around 8 to 8.2. Each week I add muriatic acid to being it back...

    Help me decide on a pool cleaner

    I haven’t had a pool in 7 years but have recently decided to have a pool added to our new home. I am building a gunite pool and have a lot of trees in my yard so I expect leaves to be a major issue. I’ve researched a bunch of the Dolphin models since I had one back in the day and loved it but I...
