Hi everyone. I was hoping I could get a little advice.
I had my 6500-7000-gallon above-ground pool balanced where I though was perfect about a month ago.
About 3-4 FC, a pH of 7.4, TA around 100, and CYA at 30-40.
I went away and left my father in charge for a month, and now I’m battling algae and some funky numbers.
I’m using a Taylor K-2006 kit, and I have the following readings:
FC: 16
CC: 0
CYA: 100
TA: 70-80
I also have a pool that looks like the photo as far as blooms are concerned.
I’m not super experienced with maintaining a pool, but I’ve never experienced such odd FC levels with algae like this. Is my chlorine entirely locked in the stabilizer from the trichlor pucks my dad likes to add 2 and 3 at a time in the floater? I thought 16 would be enough and that I’d see some CC with al this organic material.
Am I looking at superchlorinating to 30-40 ppm with liquid bleach?
Do I need to drain half the water (to drop CYA) in order to get back on track?
With only maybe 2 weeks left of decent swimming weather (subjectively), I’m considering throwing in the towel and closing the pool until next year.
I also find it frustrating that I can’t find basic formulas for chlorination online, only “this much of this product at this concentration raises this volume of water this much.” I’m unsure how I would convert, for example, CalHypo into 7.5% Na Hypochlorite liquid, if there’s no basic unit of available chlorine (for water-sanitizing purposes) that we know exists at x per oz in one and y per oz in the other. Is that information available somewhere. I figure if anyone would know, folks here would.
Anyway, any advice would be appreciated. I hope I provided adequate background info. Thanks!
