Am I doing this correctly?

After years of puck abuse I'm trying to convert to the BBB method. I'm happy with the results so far, but I want to be able to complete adding the borates before I'm satisfied.

In the spring when i first began this change my readings were FC 14 CC 0 pH7.8 T/A 160, CH 35-40 CYA 90 temp 69.

Today FC 5 (goal of 10) FC 0 pH 7.5 T/A 110 CYA 35 - 40 I've been working on the T/A which is now 110.

The past few days I've been adding nearly a 1 1/2 gal of bleach via the pool calculator.

Once I get the T/A down to 90 I'm ready to do the borate process, right?

I don't think you have to get the TA down to 90 to start the Borate process. You'll be using acid to bring the borates into range anyway. I think you'll end up where you need to be, if your TA gets too low while adding the borates, baking soda should do the trick.

It is easier to lower TA before adding borates. You can do it afterwards, but it seems to be more tedious afterwards.

Good to know. Adding to the file...
