TA 100 ** sample turned colors and added 1 more drop (110) and the color got darker-- not sure if it would be 100 or 110
I am going to be doing a few drain and refills over the next few weeks.
I know I need to raise the FC up to around 10. If we are going to swim this afternoon, should I raise now or wait until after we swim?
What about the TA? Should I bring it down to 70-90 (numbers from thepoolcalculator.com)?
Would the pH or TA have an effect on eye irritation? We've been swimming everyday and my son's eyes got red and inflamed. Yesterday he had a couple of blood vessels that looked very inflamed. Today they are still showing on one of his eyes, but not as bad. I told him that today he would need to wear his goggles when swimming.
Any feedback or suggestions?
