Chlorine not working!

[momspool]

Tested water at 6:30 tonight. It has been cloudy today and is raining a little right now.

Water seems to be clearing a little. I can bearly see the bottom in the middle now. Edges seem to be greener than middle.

Chlorine is still somewhere between 12 and 15
pH is 7.8
Alk is now reading 320
Stabilizer now 65

Just put in 1 c. Muratic Acid

Should I add more Acid than this?

18' round 7500 gal vinyl pool. I have a sand filter.

Here's a handy download that calculates many pool chemicals. Developed by one the members here on this forum. That way you won't have to guess at how much to put in. Some folks recommend adding only 1/2 the calculated amount when dealing with alk, pH, CYA. Don't want to overshoot when dealing with these levels. Always best to undershoot and adjust/add more if needed. Good luck!
