I will do whatever you guys think is best.
We have let the chlorine levels drop in the pool for the last week and we have been swimming. We haven't had any ill effects. The combined chlorine has been lower lately. The funny thing is since several days before we started swimming, we have not smelled any chlorine smell outside, not even at the pool. When I tested the pool 2 days ago, the combined chlorine was 2 and the fcl was 5.
Today the fcl was 3 and the ccl was 0. Several days ago, my cya was low so I broke up a 3 inch tab and put it in and put another tab in the floater since I didn't have any stabilizer except in the tabs. I thought my combined chlorine would go through the roof when I put the tabs in but so far so good.
If I need to get the sodium percarbonate and dry acid, where would I get dry acid?
Follow the procedure and then clean the filter, replace the sand and hopefully, we're good to go!
