I am new to this forum and need some advice. I have a 30,000 gallon salt water pool with cell generator. The bottom of my pool is concrete with a plaster finish. I have had some issues with scaling and have some discoloration. The calcium hardness is extremely high so I have been adding the magenta stuff to help with this issue. As you see from the picture my free chlorine levels and total chlorine levels are high as well. The place that put my pool in (2012) tells me to boost my generator weekly. I do not understand why I should do this when my levels are already so high. Can't I just not boost until the levels drop down to closer to normal or even wait until they get lower than normal and then boost? Last summer I had 2 people have issue with their eyes being red from opening them underwater and I think it is due to the high level of chlorine.
Also I called the company Jacks Magic about using the magenta stuff due to my calcium hardness levels and they said to keep my alkalinity low along with the PH. What is exremly odd is my hardness level is low during the winter months but spikes up as soon as the pool is opened. Like I said I have some grayish cloud looking spots on the bottom of the pool, I don't know if they are rough at this time since it is too cold to get in. How do I battle this issue? Advice and or tips would be appreciated.
