After five weeks of work to move my TA down and add borates, I believe I've settled into my groove: FC 2.5 CC 0 PH 7.8 TA 70 CH 360 BOR 50 (using strips, color a little less than 50) Salt 4300 Temp 83F CYA 30 I made the last adjustment yesterday, 25# of Borax, 1.5 gall acid, and 45# CaCl to...

Summary: My TA is 70 and my pH is 6.8. Am I ready for borax? I started to lower my TA about three weeks ago. Here are the beginning and ending numbers: Date: 4/26 (before gallon 1) FC 1.0 CC 0.0 pH 7.8 TA 130 CH 210 CYA 48 Date: 4/29 (before gallon 2) FC 3 CC 0 pH 7.8 TA 110 CH 200 Date...

Thanks for the details! Sounds like patience is the rule when lowering TA.

I was researching procedures for lowering TA and ran across a link that offered this suggestion "by creating pockets of extremely low pH temporarily, you will burn off the alkaline materials in those areas, thus bringing down the Total Alkalinity reading of the pool." There is a bit more to it...

I have started preparing my pool to add borates. Using the info in the recently posted sticky (good timing!) I am starting with step 1: reducing TA. [Sorry for the long post - my questions are at the bottom, but I believe this background is important for the questions.] My pool 35000 gal...

Any suggestions for borates?

Thanks!

I'm developing a feel for how my pool changes over the week, and would like to set appropriate targets for my numbers. My desire is to pick targets on one end the range, such that over the course of a week, the water will move to the other end of their acceptable ranges. My pool: SWG, 35000...

Any suggestions for testing borates and salt levels? LaMotte strips? I'd like to explore borates for water feel and stabilization, but before adding Borax, I'd like to get a sense of my current levels. My SWG (Goldline) remote displays a salt level of 3400ppm (I just loaded up for the...

Background Over the past several weeks, I have been testing my pool water by three different approaches: 1) the TFT kit, 2) the ColorQ 7 system from LaMotte, and 3) the Bioguard Alex system at my neighborhood pool store. My pool: 35,000 gallon, pebble-tech surface, DE filter, chlorine...

Has anyone compared results from different test kits with those from a pool store? If so, which do you choose as your "ground truth"? I have used several test kits at home (ColorQ, Pentair78DPD) and at a local pool store (BioGuard/Alex) with pool samples drawn at the same time and under the...
