First time opening pool since joining this forum

Just in case, for now add ABOUT 16 oz of 31.45% MA or equivalent. Add a little over 1/2 gallon 8.25% bleach or equivalent. Then test about a half hour or hour later and see where you are. Let us know what type of CYA you have and we can figure out quantities. You don't want to overshoot your goal.

I bought some HTH granular conditioner that is 96% cyanuric acid. The package calls for 4 lbs for a 20,000 gallon pool to get a reading of 20ppm. I've added the chlorine and some muriatic acid as well to start bringing the PH down. I'll test in a half hour to see what reading we have.

While you're waiting, how does your water look? Is it clear?

[beaverplt]

Water is green and cloudy

Bummer. More questions:
1) did you retest? If so, did you register any FC/CC?
2) can you see the bottom? If so, is there any gunk you can clean out? If not, use your leaf Rake and see if you can dig up any organics in there.
3) did you add cya yet? If not, don't.
4) how is your supply of 0871 and powder for testing? You will need a good supply for your next steps.

I did retest. FC is 4, CC is 2. I can't see the bottom. I did add the CYA. I'll have to start cleaning the debris of the bottom over the next few days. It's going to be a cool week, so I'm not too concerned about having it ready for the weekend.

Okay. Read CarlD's excellent post here: http://www.poolforum.com/pf2/showthr...You-have-ALGAE!!!

Towards the bottom it talks about algae and the importance of brushing, etc.

Get the crud out ASAP as it will use up your chlorine as fast as you put it in. Your high CC proves this.

Bring your FC up to 15 and keep it there, not letting it drop below 12. Keep your pump on continuously.

If adding 1/2 gallon of 8.25% brought you to FC of 4, your pool volume might very well be less than you think.

A green, cloudy pool would not be clear by this weekend anyway; it will take a while, sorry.

Stock up on bleach, Taylor reagent R-0871, and patience.

Let us know how it goes and if you have any other questions. Wishing you good luck!
