Took a water sample to my local pool supply store a couple weeks ago. The only thing they suggested was to increase my CH. Took care of that. I asked them about the CYA level, and they said it was OK for now. However, after reading through the pool school articles, I'm convinced it's high. CYA is 80. Seems like it should ideally be around 40. So I'm thinking of draining half of my water. Does this seem like the right course of action?
I'm planning on using liquid bleach (8.25%) and maybe supplementing with chlorine tablets in a floater to maintain levels (I already have a large bucket of tabs).
Test results were as follows:
FAC - 1
TAC - 1
CH - 160
CYA - 80
TA - 90
pH - 7.4
On a side note, I just bought my own test kit (Taylor K-2006 FAS-DPD) so I could start doing tests myself. Are the tests they do at the pool supply stores more accurate than the home tests? Is it still worth the time to take a water sample to them once a month?
