Well here I am again. Let me start out by saying the advice provided here was invaluable. I've kept the pool nice and clear for just over a year. I had some circumstances that prevented me from taking care of the pool for about 3 weeks and now I am paying the price for it. I have a chlorine tablet feeder which allows me to place 3" di-chlor tablets in there. I also use liquid chlorine. This combination allows me to keep the pH just perfect pretty much. Very rarely do I need to add Muriatic Acid or Soda Ash/Baking soda. During those 3 weeks, I didn't run the pool pump much, which would have supplemented some of the chlorine via the feeder. I like to leave the pool covers on to save on water evaporation and chemical detoriation (whatever it's called), but to get a hold of this problem I have left it uncovered for about 3 days now.

If you don't have time to read all that, here is the summary:

Tested this evening:

7 PPM FC (Brought it up to 20 PPM estimated on Sunday)
Just about no CC
7.4 pH
125 TA
500 CH - drought is now worse than when I complained about it last year, so not sure about draining
30 to 48 CYA (I could still see the dot or imagine the dot at 30, but the night before with house lighting, I lost the dot at 48ppm CYA)

Pool and spa are about 18,000 gallons total. Spa looks damn near clear through all this.

I added 2.5 one gallon bottles of 8.25% sodium chloride to the pool, which I estimate to raise the FC to 19ppm, but for some reason now that calculation seems wrong. I will check the FC in about 30 minutes to see what it's at. Chances are it's hit 20ppm and a little beyond (from past experience.)

So when I uncovered the pool there was a lot of algae growth. We brushed the heck out of the sides and ran the pool pump a lot. Now the pool is a cloudy teal color. Would you say I am on the right track to fixing my issue?
