First off, great site! It has been a great resource for information.
My wife and I just bought our first house with a pool, and look forward to it being trouble free! Unfortunately, the previous owners did not keep up with the maintenance as they should have so we have been trying to learn and correct at the same time.
When we moved in, the pool was a bit cloudy with a little algae growth. They had been using 3" Trichlor pucks for sanitization. I bought a good test kit right away as recommended, and realized there was no chlorine in the pool. I have been treating it and trying to get everything in balance. After buying a good test kit, adding chemicals, rebuilding my pool vac, and cleaning all my filters the water is almost perfectly clear.
This is where I need help:
I cannot keep chlorine in the pool. Everytime I test, it is almost non-existent. I am concerned about my high CYA and CH. I have noticed a few brown stains on the plaster. It seems that some of the plaster could be missing in these areas. They are small areas, but they concern me. I have read organic stains will lift if you can get the chlorine where is needs to be. Here was my last test results from the store:
Any help would be greatly appreciated!!!!
Thanks in advance,
