Never had any issues until now. I have been using pucks in the automatic thing (keep about 3 in it all times at a level 1 in winter and 2-3 in summer) powder chlorine shock about once a week.
Now last weekend me and my friends swam all day and night and ALLLL of us immediately were itching and it last days. Tested again (pic of test from this past tues and the other pic is from this morning showing the chlorine levels lowered.)
The pool store said to massively lower the chlorine so we did…. Add no phos so we did on Wednesday night…. And now the want me to bring up the alkalinity. I do not want to mess this up. I drained the pool twice this week to about two inches under the skimmer. I also bought liquid chlorine to use instead of the powder and I turned the pucks down to almost off.
