I have multitude of problems with my SWG and our water. My calcium hardness is above 750 (TAYLOR K-2006 ). My TA constantly goes down, and I have to add soda to raise it above 80. I am thinking it goes down because Intelli PH dispenses acid very often. I keep my PH around 7.6, (well, Intelli PH keeps it), and I see white residue in my pool all the time. I have to buy muriatic acid and add it to the tank too often for my comfort. I have tiny green and possibly black algae spots all over the pool at the moment. My combine chlorine shows 0, FC 4.5. After my IntelliChlor IC40 was cleaned by a pool professional a month ago, (he was replacing a fuse), it shows as if I have high salt level (blinking green) when I know that my salt level was fine before the repair and I did not add anymore in the last year. I have 3 rust stains near one of the pump baskets (rebar problem?). They grew from just one spot to 3 during the last year. I see there is an accumulation of orange looking staff on the top of these spots and they falls down as little rust specs if I touch them.
My CA is very low, around 20-30 because I have Intellichem (it is one of the requirements for it to operate properly). My IntelliChlor IC40 works 100% pretty much all day trying to get enough chlorine into the pool, but with the latest algie bloom I had to add liquid chlorine to get my FC to 4.5.
I do not even have energy for a proper shock procedure because I think it will be a temporary measure anyway.
What should I do? Do I refill water considering my fill water CH is somewhat reasonable? I have not measured it yet, but we live in Arizona, Phoenix area, it can be really bad depending on the time of the year. Will algae disappear by itself when the pool is drained?
How can I know for sure if I have a rebar problem?
I do not want to look at our pool right now, I wish we did not have it !
Thank you for the input.
