Re: spring startup

I don't think so, but it will slow reaction times, so you may want double or triple the time you wait before reading, especially on the chlorine and CYA tests.

(This was in reaction to a question if 50 deg water changed the figures)

Is your water still 50?

If so, it wouldn't be a bad idea to let tests stand for a full minute, before final mixing and reading.

I am still getting super high CC levels.....
I have been able to get my FC up to over 10 at times but my CC level has been on the rise. I have gotten CC readings that seem to be outragous from what I have read on this forurm... over 11 at one point but not that high now. I still get in the 5-7 range which is still a very high reading. I did use a commercial "shut down" package from In The Swim before shut down in the fall. Could this effect my CC numbers??? Is there an end in site???

Recent Measurments:
FC 6.5
CC 7
pH 7.6

Is there ANYTHING I could be doing wrong with the Taylor test that could be giving me a false positive for CC? My powder that I add 2 scoops is not a fine powder but rather small crystals and does not dissolve real well. Most times it will not fully dissolve no matter how much i swirl.
My water is rather clear with sediment on the bottom and no odor?

Thanks,

Mike

I ran out of cl testing reagent can't test until I get more. Water starting to clear but cc still up at last test. I just hope I am testing right.

Your testing method is right if you're:
1. Adding the scoops of powder to the sample,
2. Using the first reagent, counting drops to clear
3. Adding 5 drops of the second reagent, then
4. Counting drops to clear.

HighCC numbers are typical of ammonia cleanup. There IS an end to it, but it does take huge amounts of chlorine to get there.

Not likely. If you get a pink color, the DPD is working.

I haven't re-read the whole thread (forgive me Janet, Dave, Lisa!) but your levels are completely consistent with a pool that experienced bacterial metabolysis of CYA to ammonia or urea. There is absolutely nothing going on with your pool that is surprising or unexpected to us.

I ran out of the 3/4 oz. of reagents already and have orderred replacements. Water appears to be clearing. I will update when I am able to test. (strips read no free cl but I understand they cut out at 10 ppm. I have been still adding bleach 1.5 gal a night and pucks in the skimmer.

Able to test again:
FC 7.5
CC 2.5
pH 7.0
TA 160

Water still cloudy but clearing up significantly. Shallow end pretty clear but cannot see the bottom in the deep end.
