Hi all,
I have a relatively new pool owner. Have had it for about 2 years. I do my own chemistry and up until last year (2023) my pool was perfectly fine. This last winter the pool got a bit more dirtier than usual and upon opening this summer I have had a many issues and have spent more money than I would like to admit.
the pool water is clear and well balanced for the most part. At a certain point, my test strips were reading low CYA so I raised it only to find out that the test strips were faulty. Now I am using the liquid testing kit and my overall chemistry is as follows:
Total Chlorine: 1-4
CYA: currently 45 - used to be over 200 (drained water to bring the levels down)
PH: 7.2
Alkalinity: 200 (I just added some muriatic acid to reduce this)
Hardness over 80+ PPM (I gave up testing as the color would never change (this may be related to the high alkalinity) working on fixing it
I have a decent amount of staining. It is light yellow/tan, doesn't feel slimy, doesn't brush off. I have tried bushing it by hand and it doesn't come off
I read about Mustard Algae and started treating it with yellow treat (bromine): did not work (but this was when my CYA level was high and maybe it made the chlorine less effective? (I can try again)
I read about metal staining and tried both Vitamin C and Citric acid and both did not work. I did nothing at all I also added metal gone and culator recently
I tried brushing and that didn't work.
I changed the cartridge in the filter since it was three years old and not doing a great job.
Before I go adding more stuff to the water and continue to waste money I need your help. What is this stain ? The stain is all around the pool walls (not just in one spot )
