Decided to try an experiment.
I was having a problem with my TA it was up near 190.
After reading much here, I decided to just try adding air to the water.
I went to the local pool store, looking for some type of in line air adding device. They didnt really have anything.
They called the shop "pool expert". He said I was just waisting my time and that adding air to the pool would not do anything. One persons opinion I thought.
So I found the most cost effective item I could get was a fountain that attached to the outlet
Ive been testing the water a couple of times a day for the past 3 days.
FC 5 (added bleach)
Only changes have been the addition of the fountain and adding the bleach. Standard 10.5% solution.
Saw the ph drop to 7.4 on day 2 but then up again as the TA decreased.
Would the reduction in TA be a direct result of the addition of air, or could it be that the back pressure on the filter was increased by 3 mmHg by restricting flow from the outlet jet that the fountain is hooked up to?
Im thinking the added air is going to result in extra chlorine use as air is food for alge?
