We have only been pool owners for one year and it was a miserable and expensive year spent fighting mold and algae. We could not wait to get our pool covered last fall just so we could quit throwing money into it. I found the TFP website over the winter and ordered the test kit. We uncovered the pool this week. I tested the pH today and it is at 7.2. I used the pool calculator: for our 23,000 gallon pool, add 715 oz of Clorox (about 4 bottles). We added the four bottles a couple of hours ago and it turned green immediately. Two hours post adding the Clorox, it is still the same color green; but the consistency now looks "milky." It looks pretty nasty; and we can no longer see the bottom (pictures attached).
