So having just moved things were crazy and I just dumped a scoop of chlorine (which I found in the pool shed when we moved in) every now and then until I had time to measure up etc. Finally got it done, and the scoop here and there was insufficient, but numbers and details are below. Advice would be greatly appreciated. I've read the articles on here regarding amounts, buying bleach, borax, etc from HEB. Though if location and current condition means I should deviate from that please tell me.
I'd like to use borates in the pool, there are none now. I'm also considering salt - would like advice on that. These results are measured using the TF-100 kit.
FC: <0.5 (Color barely changed, if it did at all - so one drop it was definitely clear)
pH: 8.2 (maybe higher - it might have topped the test out - the color may have been a little more intense than the highest)
CYA: <20 - I could still see the dot when the tube was full
Salt: <190 (only went to 1 on the strip which wasn't listed on the chart - lowest reading was 1.9ish at 380)
The pool has a roughish bottom, so I assume it's masonry, but I am not familiar with pools to be certain. It's definitely not tiles or fibreglass
It's an odd shape, but fortunately with every corner at a 45 degree angle, so with a bunch of measuring and a salute to Pythagoras I ballpark it at 43.32kL, which is 11,444ish US Gallons (is that the preferred units?).
I'm in Austin, TX, so it's **** hot now, and I should be okay to keep the pool open all year round.
Thanks for any advice.
