My old box of Borax's ingredient was sodium tetraborate (with 4 atoms ???) and the new box is sodium borate (without 4 atoms????) Is it the same thing and one is just "slang" (which would shock me) and if not , is there an impact on pool math Thanks

Yesterday FC 0 TA 0 pH below 6.8 CYA really high (Leslie test 147) I slammed with a gallon of 10% 5000 gal yesterday and this morning I added: 21 oz 20 Mule Borax (sodium tetraborate) btw I just purchased another box and it is sodium borate.....what is the impact of the different chemicals...

I have searched but can't find the recommended order of correction FAC: 4 TAC: 4 CH 50 CA: 0 TA: 20 pH: 7.0 Base Demand: 2 thanks

I have not paid any attention to my "low" CH as a recommended by the smart guys/gals in this forum(I have a vinyl liner) But now I have added a Laars Pool Heater. Do I need to be concerned. FC: 6.5 pH: 7.2 (will add 9 oz of baking soda today) TA: 100 CH: 30 CA: 50 thanks

I am trying to get my pool balanced. I am using k-2006 and had my results confirmed by local/national chain store. TA =0 pH= my test well below 7 (almost green in color and took 52 drops of base demand reagent to achieve something close to 7.4)--Pool store took 55 drops and recorded pH at...

I began SLAMing my pool 4 days ago (84 hours). My CYA is somewhere between 25-40 so I used the SLAM values for Mustard at 30-40 CYA, which is about FC 22 or mustard and 14 for a normal SLAM. I checked the FC every 3-4 hours and after the first couple of checks where the FC drop was 5-8 the...

Reposted as I previously Hi-Jacked someone else's post (Sorry)--I deleted the hijack, I have violated TFP discipline and allowed my FC level to go below min and now I have yellow mustard... What to do? If I have understood the ton's of post wrt this ugly stuff, I am to SLAM "normally", clean...

5K gal vinyl, with cartridge filter and 2 speed pump Pool was very green yesterday, the bottom was almost/sorta visible. I used a gallon of 8.25% bleach and this morning the FC was 6.4% (using the good test kit &.2 ppm scale) Pool is still green but bottom is visible, added additional 32 oz...

Good morning, If I have grasped the CYA/FC relationship notion: 1..that as CYA increases, there is less HOCl available/free/unbound for use as a sanitizer and/or algae controller, 2. and that HOCl is really what I am trying to maintain by adjusting FC, 3. and the HOCl level decreases...

Yesterday I received 8 oz of each the R00013 and the 50ppm test solution from TFTestKits. I have used just about half of the solutions in about 6 different attempts to calibrate my reading at 50ppm. All of the samples keep reading at 30 or just a smidgen above 30 using the large tube that came...

I have a 5k gal above ground with large cartridge filter and 2 stage pump (1hp & 2hp). I took a sample to Leslie (monday 9 june) for confirmation of my own results using a Taylor kit: Water very clear and bright ok Chlorine 1 & 1 low pH 7.0 low alkalinity 80 OK Cyanuric 60 low calcium...
