I have an 18,000 gallon AG pool being installed in the next couple weeks. I just received my TF-100 test kit today and tested our water. We're on a well, and the water I used is before our softener and filter. It is the water I plan on filling the pool with.
A note is, we have some iron stains in our toilets so I know there is some iron in the water. Not sure how much. The color of the water is a tiny bit tinted, but not much.
pH: Slightly less than 6.8 (it appeared a lighter orange than the lowest amount on there -- 6.8)
CYA: 0 (filled the whole tube and could still clearly see the dot)
If I did these tests right (I'll do another to help verify this)... and I want to chlorinate with bleach, it looks like I need to add bleach of course to raise my FC. I will need to add some borax to raise my pH, which will also raise my TA slightly. The recommended level says 70-90+ for TA ... will 200+ be acceptable? My CH is slightly high at 360 (recommended level 0-350)... do I need to do something about this? The pool school doesn't say how to lower it on the recommended chemicals page. Finally, CYA should be 30-50... so I will have to add some.
Does that sound right?
