Well, I think I am looking at a complete drain and refill to correct this mess! Very happy with the TF 100 kit, my first question is how can anyone accurately deal with a pool without one?
Yesterdays results were:
FC = 2
CC = 1.5
TC = 3.5
CH = 500
TA = 170
CYA = 200? (could not see the dot halfway to the 100 mark)
CC = 1.5
CH = 400
TA = 200
CYA = 200 (same result as yesterday)
Since the two days results are so similar, I feel I am doing the tests correctly. The instructions seem easy to follow. Probably because there is so much junk in my water, it is hard to tell when colors change. For instance, when the test is supposed to turn to "red", mine turns "pink". When it is supposed to turn blue, mine is more "purple"
At any rate, Pool Math says to exchange 80% or so, but for that little difference I think I will do a full drain.
We have been using pucks exclusivly for many years until I was educated here. My problem, like most, is that we have always listened to the advice from the pool stores. Last year, when I was having trouble keeping the chlorine up, they had me put in up to 4 pucks a week and also Total Alkalinity, PH UP and other stuff. I see now all I did was screw up the water really badly.
Question: Using the quick test I get TC of 1 yesterday and 2 today, yet on the weekly test I get 3.5 and 4.5 respectively. This does not make sense to me...
