The TF-100 kit arrived yesterday yea!
The pool was green last week, but without the kit it was not possible to know what to do. I studied the SLAMing article and decided to pour a gallon of chlorine every hour; it took two days for the green to turn milky.
Now, I vacuum and brush daily. I was afraid it may start going green, so I poured a gallon of chlorine once a day, till the kit arrived.
Here are the Test Results:
FC = 50
CC = 0
pH = 7.6
TA = 200
CH = 500
CYA = 100
Before I came to know about Trouble Free Pool I followed the 24 page booklet by Aquachek using their test strips. I used chlorine pucks in two floaters and poured PoolPerfect+PhosFree two cups a week. No green pool for about five years. Then suddenly a green swamp.
1. I think I should stop pouring a gallon of chlorine daily as FC now is 50. But what FC should I aim for? The Calculator says Goal: 8 to 13. The Target column says 8.
What FC should I keep the pool at?
2. Is the pH of 7.6 ok?
3. TA is confusing. Do I bring it down by lowering pH?
4. CH When I put 500 in the Now column of the calculator with the Goal set at 350 the calculator says to replace 30% of the water with new water of CH 0. But my city water has a CH of 140 (I did the test).
5. CYA is 100 do I need to bring it down? I can monitor FC according to the Chlorine/CYA chart. Otherwise, the calculator says I have to replace 50% of the water—a shock to me!
