BBB for small pool (6423 gallons)

[Watermom]

You are correct about the CYA test. If it never got cloudy, then you have no CYA or at least no measurable amount. Since you used some dichlor, you have some CYA but apparently not enough to register yet. In this small pool, each 1/2 lb. of stabilizer will add about 10ppm of CYA.

First, just wanted to say I subscribed because this site is SO VERY HELPFUL! Thanks.
My readings today:
FC 2.2
pH 7.6
TA 310
CYA <30 (but i'm guessing more than 20 because the dot did disappear when I accidently overflowed the tube)
Based on these readings I added 3c bleach tonight, as recommended by the pool calculator.
I also tested my fill water's TA since my pool tests so high and it was 300.
I have a couple of questions:
Should I add a little more CYA until it's at 40 or is this sufficient? I added 2 lb of the powdered form.
I printed the "Lowering Swimming Pool Alkalinity-A Step by Step Guide." I understand the concept. Just want to make sure before I start the process, it's really necessary to lower the TA. (Because step 1 says - A REAL reason to mess with this.) If so, I'll buy some muriatic acid tomorrow and begin the process of lowering my pH.

With a small pool, and no evidence of high calcium, I don't know that you actually need to *try* to lower your TA. Instead, just get the muriatic acid and use it to keep your pH below 7.6. In the process of doing so, you will eventually lower the TA.

Alternatively, given your (still) low CYA, you could just get a floater and some chlorine tabs, and use those to chlorinate your pool. The tabs would add the chlorine you need, the CYA you still need, and the acidity you'll continue to need till your TA drops some.
