Seriously? Did they tell you to do that? If so, stay far, far away from that store's recommendations in the future.

"Sodium hydrogen carbonate" is an old - but still legal - chemical name for baking soda, that BioLab/BioGuard and others use to conceal the fact that they are selling you baking soda, available in a purer form at Walmart for ~$0.50/lb! It's bad enough that you overpaid for it; what's worse is that you didn't need it, and will eventually have to remove it -- your TA was ALREADY too high!

If your test reading for CA (= cyanuric acid?) is from the HTH kit, and is really 120 ppm, then your problem is that you don't have NEARLY enough chlorine in the water. The Best Guess chart, linked in my blue signature bar, explains.

To fix the problem, do this:

1. Test your pH -- it's probably too high. If so, read the muriatic acid page in my signature, and then add acid till your read 7.0. (Don't worry, it will come back up on it's own!)
2. While you're adjusting the pH, add 2 gallons of PLAIN 6% bleach each evening to your pool. Don't worry about overdosing -- you'll go MUCH higher once the pH is fixed. Test your pH BEFORE you add the chlorine.
3. Once the pH is down, add 8 gallons of PLAIN 6% bleach in the evening.
4. Check pool color and test chlorine (not pH) in the morning, and report your results. (You should get an orange OTO reading.)
5. If the color has not changed by the following evening, repeat the 8 gallon dose.
6. Check again, and report your results.

IMPORTANT NOTE: These doses depend on a CYA level that is greater than 100. If you tested CYA any other way, besides the cloudy water test in the HTH 6-way drops test OR the Taylor K2006 . . . . do NOT use the 8 gallon doses.

Instead, fix the pH and tell us how you tested.
