My TF-100 got delivered yesterday and I'm trying to practice a little bit.
Here's what I got:
Fill Water:
PH 7.5-7.8
CH 175
TA 150
1st pool test:
PH 8.0
FC 2.5
CC 0.5
CH 375
TA 140
CYA 45
Borates 15
added 32 oz MA to get down to 7.5 and 121 oz of 8.25% bleach to get back up to 7.5.
Let it run for 30 mins and tested again:
PH 7.5
FC 7.5
CC 0.5
CH 425
TA 120
CYA 35
Borates 15
What do you know, pool math works.
Waited 24 hrs and tested again:
PH 7.5
FC 4
CC 0
CH 300
TA 110
CYA 40
Borates 15
Added 32 oz MA and 3 qts of 8.25% bleach to drive PH down to 7.2 and FC back up to 8. It got a little too late to retest to confirm the results, but I may try to test it first thing in the morning.
My thoughts:
I'm worried about my CSI. It seems that if I let my PH/TA get up at all I'm in the danger zone. I have noticed that it seems like the color of my plaster isn't as dark as it used to be and i'm wondering if that could be a result of letting my CSI get out of range. I started with a dark blue and now it seems like it is turning to a little lighter shade of blue/grey. Is it possible it faded in the sun, or is that some kind of calcium deposits?
I'm trying to get my TA down to near 80 so I'm planning to keep working my way down to 7.2 on the PH and let my spill over from the spa to the pool do some aerating to kick the PH back up without raising the TA.
The CH test is obviously the hardest test to do accurately. Every time I think I'm done I look down and see it turned back to pink. Going forward, I'm saving this test for last so I can let it spin for a while between drops. I feel like my results are all over the place right now.
CYA - I did the first 2 tests indoors last night. I tried to replicate the high ambient light environment I've seen people mention and got the 35 and 45. For today's test I did it outside with my back to the sun and got a 40. Do I need to try to raise my CYA up to 50, or is 40 good? I'm in TX, so we get plenty of sun/heat during the day. I have a big pile of tri-chlor pucks left over from before my TFP awakening. Seems I could supplement my FC with pucks for a little bit until i hit 50. Or is that too dangerous?
Do I need to work my borates up? Whats the right level?
Am I on the right track? Anything else I should be considering?
Thanks!
