FC over 5-10 ppm after sitting overnight
CC looks the same
Moms Intex pool is on well water and all summer we have not had trouble with metal. And did not have a bit of trouble last year. She was ill for a few days and thought it looked green and cloudy so she bought this Walmart brand shock called Pool Essentials 3 and added it, and it made the water much greener. I went and added the HTH metal control stuff per directions and told her to shock it again because her FC was showing 0. And her CC was over 5 to 10 ppm, the highest my test kit will go. It got much much greener. Now you cannot see the bottom and still could not after it sat all night. I expected that everything would fall to the bottom overnight so we could vacuum it out.
Now she is draining the pool because I read the reviews on the Walmart brand shock and people are reporting that the stuff does not dissolve, it just lays on the bottom and bleaches and damages the liner. She had to get into the pool today and said that it felt gritty she felt no slime at all in the pool though, so we would rather be safe than sorry. One review mentions it turning their water really green. Someone else says it will not help with algae. We are not sure if this is metal or algae at this point.
We are wondering if there is something in this pool shock that could have maybe added metal to this water. I found this: Pool Essentials active chemical is Trichloro-s-triazinetrione which is classified as a Sanitizer, Algaecide and Bacteriocide. We will avoid this product in the future but do not want to end up with green water again if it is metal in the water. Could the HTH brand metal control be the problem?
I took a white bucket today added the well water and added chlorine to it to see if it would turn green. It did not. And when I tested that water on my test kit, a Leslie's kit, it showed 0 FC even though I put a lot of that shock in to the bucket. A CC test came up an odd dark orange color.
I only use bleach on my own pool and the HTH Metal control and have not had a problem.
