Clearly it didnt add enough cya as I was not able to make the dot disappear.And... how much CYA is that going to add to your pool? Do you at least have a volume for each stick?
hmmm, I don't like that at all. You really do NOT want to overshoot CYA, but you also do need it actually IN the water for your SWG to work effectively.
The guy was pretty adamant that I do not put more than I need as i would be screwed after that. I'm assuming the SWG is working well since I have such a high FC? Especially with it being 30c and over everyday for the last week.
