Just moved into new house with bigass pool
Looks like old owners had pool guy that did little more that add tablets to floating chlorinators. Got it vacummed snd brushed but we have some heavy algae in cracks and crevices and the steps get brownish.
Got a tf100 kit.
Pool store measured cya at 99 last week. But im not sure how absolute the test is for cya. At 100 the black dot is very faint but I can still see it till 80. (Did it 3 times).
I measured the fc this evening before bed. It was a 4. (The full set of numbers was this am, we had a sunny houston day today). I will measure fc am tomorrow and see what the oovernight fc loss is. I need to get in there and scrub the algea out of the cracks and crevices. And change out The pool and spa lights. What do you guys like for colored led pool bulbs?
Any way happy to be here and I like the bbb method. Very easy. He re in houston we get 3 121 oz bottles of 8.25 chlorox from sams club for 8.18 plus tax.
