Newbie here Many thanks for this great forum to help me.
I was about to shock my Salt Water Pool so thought the best place to read up on it was here but now I am more confused than ever
My CYA is about 70-80
My FC based on the recommendations here is being kept around 5-6FC
My CC is about .2
BUT My overnight FC drop is about 1.5 -2.0FC
My pool is clear but get a lot of dead algea dust on the bottom it has also been super hot here recently
If I use the table here on shock level based on my CYA level i would have to raise the FC to about 30FC however not one product recommends this. I even caontacted HTH and they could not understand this. According to them I should be only shocking to a level of 5FC which I already am at I was told I run the risk of damaging equipment at this level.
I have just exhausted Google trying to get an answer
Is this reading of 30 meant for NON salt water pools?
