Re: Ascorbic acid treatment
I have a fiberglass pool, sand filter and have well water. I have learned how to keep my pool stain free. The first thing is to have a good test kit so that you can do your own testing so that it will be consistent. You want to remember that high ph along with high chlorine will let any metals in the water fall out of solution and stain the pool surface. Hedp is your friend. You want to make sure you always have good chlorine levels so you don't get algae so you don't have to shock. Once the stains are on the pool, and the Hedp ( sequestering agent) does not lift them, it is tme for an ascorbic acid treatment. You should never start an ascorbic acid treatment if there is any chance you have algae- because you will just be wasting your time and money. When doing a treatment you will need to have lots of bleach on hand, and borax. I am really surprised that your ph did not go down, it must have been really high. You cannot do just ascorbic acid without the sequestering agent because the ascorbic acid will lift the stains but there would not be anything to keep the metals in solution, and the pool will stain as soon as you get the chlorine & ph high. The ascorbic acid is not dangerous to swim in, but you only want to swim once the water is holding chlorine so that you are sure the water is sanitized. I think you were starting on an algae boom, that is why your water was cloudy. Ascorbic acid eats up the chlorine really fast until it is all gone. Just keeping pucks in the skimmer is not enough. You need to test the water all the time adding enough bleach to bring your level up to your minimum level according to your cya. Hence needing a good test kit! Don't get overwhelmed, it is not hard once you know what to do, and we will help you! let me know if you have any questions,
