The pool is almost full - water is clear but still a light dusting of green algae on bottom of pool.
Please talk chemicals to me - I dont really understand them yet and I need to dose the pool today.
Unfortunately, all I know is chlorine. You said your daughter gets red, itchy eyes in chlorine pools. This might not be an allergy at all, but just poorly maintained pool water. (Incorrect PH and LOW chlorine causes itchy red eyes).
That being said, there are many chlorine free alternatives but as you have learned some work marginally and many are pure snake oil.
If it were me, I would try properly chlorinating and see if she has problems. If so you could always switch to something else as chlorine dissipates readily over time. I would shock to 10ppm, keep it there for 24 hours and then maintain a free chlorine of 3ppm.
