Lowering alkalinity, Ben's method...

[steveinaz]

There are alot of variables, maybe I'm misreading the drops needed to get to the PH I want, or possibly my pool is closer to 15,000 gallons than it is 10,000 gallons (the values on the chart). I've been using the 10k chart to be safe. The PB estimated it at 12,000 gals.

Anywho, some things have come up that aren't going to allow me to finish this now--properly, but probably sometime after the first week in April I'll give it another go.

The acid demand was not too bad prior to this, I was only needing a little over a cup to get my PH a perfect 7.5. Overall I'm really pleased with the numbers, and how easy it has been to keep them in the "good" zone. This mornng my numbers were:

FC=5.5
CC=0
PH=7.6
TA=190
CYA=45

The trend for the last 5 days has been: at 4pm I add 2 pints of Clorox (adds approx 1.1ppm FC) and 1 cup of muriatic acid, and the water is crystal clear. I'm losing about 1ppm of chlorine per 24hr period.
