So I pull back the solar cover and instantly think: "when was the last time I added chlorine?" Not good. Green everywhere. Immediately added 5 174oz bottles of bleach, and brushed, brushed, brushed. However, on the positive side, my water is a toasty 83 degrees! But, on a negative side, with the cover pulled back and the sun hiding my temperature is going to plummet!
My manual vac head and hose had issues, went to the pool store to get new ones, which they had at reasonable prices w/ end of year discount. Well, I've been battling algae breakouts all season long this year, even with chlorine kept on high side, and NEVER HAVING ANY CC READINGS AT ALL. Guess I've shocked 4 times due to either slippery feeling of vinyl floor or green stuff accummulating on sloping sides of pool. When I told this to pool lady, who has never tried to sell me anything before, she claimed that there's been higher than usual problem with "yellow" algae. I said, "you mean mustard algae?" Upon end of the discussion, she convinced me to buy this non-copper algaecide "yellow rid". I thought she just might be right. Bottle states: sodium bromide. Never gave it a minutes thought. Put the 4 capfuls in my pool, waited several hours, and took chemical readings, chlorine was low (16, w/ CYA of 60) so added 3 more jugs of bleach. (based on my calcs, for a 24K pool, one lg jug adds 3.4 ppm of CL to my pool, hence 3 lgs jug would raise ~10ppm).
It's at this point, I decided to read up on "sodium bromide" and not liking what I've read so far. I have no idea what bromide is or what it allegedly can do to a chlorine pool, as noted on several sites. Chem geeks out there, did I just royally screw up my pool w/ 4 capfuls?
Here's latest numbers:
PH 7.8, but I'm leery of this be valid
CALC 70 (not sure of this one either, reading on Sept 4 was 120)
CYA 60-70 (hint of circle at 70, totally obliterated at 60.....did test inside due to rain, which is not my usual testing method...poolside and sunny, under umbrella.)
I'm shooting for FC of 24. I'm brushing and checking FC every couple of hours. I'm just not sure about this bromide ****.
