Open question to the forum.
I've started off with the Pool Master 5-way kit. Initially my FC/CC were off-the charts dark orange, so I turned off the automatic chlorinator. The PH was at 7.4 to 7.6 and the TA was 170, I had these same readings for several days. The pool's water was clear, but I have noticed some scaling on the tiles, I knew the heater core had been changed out a few months ago and you can see plenty of copper stains. Over a week or so I finally saw the FC/CC drop into readable parameters.
So I went to the pool store...
Unfortunately they sold me the same kit I already had, I just didn't know/trust how old the previous kit was, and it was kept in the Texas garage along with the other pool chemicals. Based on what I told them, they had me buy some MA to combat the high 170 TA, telling me I should shoot for a 120 TA. My tap water is 250, and we had a whole bunch of rain over the previous 2 weeks, it's cooled down and the pool's water is about 78 degrees F.
So I pored 1/2 Gal of MA and waited a day... It dropped 10 points, so the next night I pored the other half in. After 2 days I now I have a FC/CC of 2.0, a PH of 7.2ish and a TA of 150. I sure wish I had read the pool school before I started jacking with my pool. Adding to the drama, I bought the Aquachem 6-way test strips to tide me over until I get a real kit, and it says my FC is "very high" and my stabilizer is 150+
The good news is I've started aerating the water with the overflowing SPA. Anyone have any thoughts based on what I've done so far?
