I've been "living" with my TF-100 for a few weeks now. Today, I learned to "pay attention".
This morning, 5/12:
CH: Did not test
Added some stuff - see below.
CH: 350 (ran twice - how did this go up?)
CYA: still 35. Probably don't need to test this so much.
So after a test (above) and brush (this morning), I "felt" the chlorine should be a little higher, so I dumped in about a gallon.
More is better, right? Before TFP, this probably would have been "about" right. Dummy. Use PoolMath. I wanted Cl to hit about 5 - 5.5. PoolMath tells me I should have added 2 cups (16oz), so I added 8 TIMES MORE THAN I NEEDED!
Acid - same thing. I'm worried about algae, so, more is better, again - 1/2 gallon or so. PoolMath tells me I should have added about 2 cups (16oz), (to get to 7.3) again, added about 4 TIMES MORE THAN I NEEDED!
Lesson learned - USE POOLMATH!!! I've got this pool so well balanced, it takes "just a little bit" compared to the old Pool Store Days!!!
I'm putting in 16 oz of stablizer and then will test on Sunday.
LESSON LEARNED! Just like a guy (the girls will say) - doesn't follow directions.
I am SO GLAD I'm here and have learned all this - wife says the pool water is great (well, not so much today, but nobody was swimming). Hit it with a .lb of baking soda in a bit (PoolMath!)!!!
I simply cannot believe how "little" chemicals are needed when you get the water balanced.
