Pools that are loaded with totoal dissolved solids “TDS” are tons of fun. Especially when every thing was looking great three days before, then you show up and everything has gone haywire.
I have a small fiberglass pool in Southern Shores. We opened it up this spring to find a coffee color stain on the shell. So we proceed to clean it up and add salt to get the level up. We add a little bi-carb and soda ash to get the PH to a low 7. Then we added a stain treat and come back the next day and the stain is gone. So we set our salt chlorinator on 20% add some bi-carb and head to our next project.
I return two days later and the stain is still gone. The chlorine count is a 2, alkalinity is a 7.2. We add some more bicard and a touch of ash. We vacuum out the pool, all looks great so we leave. Owner comes down two days later and calls to say the pool is cloudy and stained. I think he is pulling my leg so I head over to see for my self. Sure enough the pool looks horrible! Not only that the pool is now foaming. I test my chems and they are good. What’s going on here?
So now I am standing in front of a some what cloudy foaming pool with the owner next me scratching my head. You should have been here yesterday It Was Perfect I say. So I do the only thing that I can think of I have not tested, my TDS. Sure enough it’s at 2800 where the exceptible among is 500.
I am currently dump 2/3 the water at this property with the hope that once we refill and get our TDS down to a proper level. We can rebalance, remove stain and all will be right once again and stay that way. I ll keep you informed
