I tested my hot tub and PH is almost clear and TA turns to red instead of green after adding 2 drops of R0007 and 5 drops of R0008. I'm guessing it mean I have no TA or PH? Bromine level shows high but I only have test strips for that, my FAS-DPD test kit doesn't test for bromine levels. I've read high bromine levels could cause wrong readings of TA and PH, is that correct?
While researching this I added water which overflowed. I scooped out alot to get it down to normal. I added some PH and retest still shows bromine high on the strip. PH now shows a Barney the Dinosaur purple color. I retested TA and now after 2 dops of R0007 & 5 drops of R0008 the water is a bluish green. It only took one drop to get it to a reddish purple. I'm thinking I'll pull the bromine float and check it again in a few days. May be time to change the water :]
