A sample diluted with 50% distilled water turns from green to orange after three drops (I have confused myself Now whether the result of this is 30 or 60.What does the TA test show?
Confession- Probably because when thought that I couldn’t test for Ph or TA with a free clorine of 22, I periodically added some Muriatic acid (I know- seems really dumb now!!!)If you used a 25 ml sample, that would be 15.
Why would your TA be so low with a new pool?
I did this because prior to the SLAM, my pool had tended to have the ph rise easily, because it was a new pool. I told myself I was keeping to the same acid adding schedule I used when I regularly tested ph….Confession- Probably because when thought that I couldn’t test for Ph or TA with a free clorine of 22, I periodically added some Muriatic acid (I know- seems really dumb now!!!)
I have some baking soda and borax but will re do my tests and wait to see what @joyful noise says before adding stuff! Thanks again for your advice!OK. Let's see what @JoyfulNoise has to say. But I suspect you need to add some baking soda.
TA = 30 (undiluted sample) I only diluted the ph sample! Confused myself. Thanks for your patience!Ok. You misunderstood me or I was not clear enough …
You only use the dilution method to measure pH when the FC is above 20ppm. You DO NOT use a diluted sample for TA.
For the TA test, with an FC above 20ppm, I would recommend the normal water sample (25mL of straight pool water) and add 2 drops of R-0007 at the beginning, not 1 drop.
Retest TA and post that result. Forget about pH for now.
Maybe see if the University of Arizona Chemistry lab will analyze the sample for you and bring a water sample to let them test for sulfate.I put a drop of Muriatic acid on the crystals and didn’t see bubbling. Same thing when I let this dry to a white flakey powder.
Note: You can also try ASU; I hear that they are pretty smart there as well.
