Can this Reagent go bad? After adding 40 drops of 0871 and not the slightest hint of change, I poured out the sample and opened a new canister of powder and this time, it only took 11 drops (5.5 FC)...so I'm guessing its bad?
Also, this weekend, I added 4lbs of stabilizer. How long will this throw off my other chemical readings?
FC - 5.5
CC - .5
TA - 150
CH - 130 - this is low according to the "pool math" page.
PH - 7.6
CYA - registered 35...I know this may go up over the next 3-5 days.
Calcium Hardness is my only real concern. Can this be the result of the stabilizer?
Thanks in advance
