Re: New Homeowner - Green Pool
YAY! TEST KIT IS HERE! Little upset that the Taylor block kit is basically the same thing I already have - but now I have two sets of the reagents for the "spot" tests for CC and pH, so I guess I'll live. Also just bought a 50lb bag of DE to help supplement my sand filter. Before I do anything below I'm going to dump a cup at a time (give or take) into the skimmer basket and wait several minutes for the pump to stabilize, until my psi reads one lb higher than it did before DE. This sand filter is SLOW and I really would like this pool to clear before the weekend. In other news, after all that swirling I think I will definitely be looking into getting some kind of automatic swirler.
Full panel results:
pH 7.2 - 7.5 With the taylor kit.
fc 1
cc 3
ta 320-400 At 320 the sample turned a definite pink and stayed that way. At 360 it was a nice HOT pink, and then there was no detectable change between 360 and 400 so I stopped there.
ch 310-330. It turned what I think was blue (vs. purple/grey) at 310 and then didn't change again at 330 so i stopped.
cya 15-20. I don't THINK i could see the dot at 20 and I definitely couldn't at 15, so yeah.
So. CYA is a little low for normal use, but I think it'll serve me just fine for the shocking process. Based on chlorine/cya chart and the pool calc, here's what I plan to do.
Since I can't tell if i had 15 or 20 cya, I'm going to assume 20 since that's going to be mean more chlorine to be safe. So we'll estimate that I'm starting with 1fc, 20cya, and have a non-swg pool.
Shock fc of 10 means I need to add 206 oz of 12.5% bleach. I think that to be extra safe and because I'm lazy and don't want to measure bleach, I'm going to just dump two gallons in for the start of this process - which will bring me to a shock level of JUST over 12 fc. Then I will brush, spend 20 minutes putting together my wifes new computer desk, and then go back out and test again. At this point the pool is well out of direct sunlight, so I should be good to start.
If at time of the second testing I've dropped any FC levels, I'll use the pool calc again to determine the correct amount of bleach to add, add it, and brush again.
