Hey everyone, I just bought a house a couple weeks ago and after testing the pool I'm realizing the previous owners pool guy didn't do such a great job with the chemicals.
Pool is an inground Gunite pool I believe. Around 15k gallons.
I have alot of experience testing water as I previously owned a very large reef aquarium so I pretty sure my testing with my new TF100 kit is fairly accurate.
CH is sky high = 540! BTW, my tap is only 160
CYA is off the scale and if i had to guess it's 110-120
Pool calculator is saying I need dump around 65% to get my cya to 40
I've been reading about draining the pool and how hydrostatic pressure can cause the pool various issues. I just want some opinions on this. Like I said I won't be draining the entire pool.
Not sure if temperature comes into play, but it's been getting down to low 30s at night, so the ground is cool. I would probably pick a day that was in the 50-60's to do this.
Thanks for any advice you have!
