Our journey from green to clean is complete, after removing hair plugs, replacing the filters often and of course keeping the chlorine level up. DH has been unusually helpful in replacing filters and hauling bleach, since my arm is still giving problems. At the sight of a clear blue pool yesterday he was quite pleased with himself (mind you, we've had a pool for 6 years). "Isn't it amazing that we can go from a swamp to that! just with me changing the filters!". I replied it isn't magic, there are precise chemical balances at work here... and recited all of the test levels, and how much bleach raised the ppm of chlorine to what level, and where that related to the various chemical levels in our pool. He just replied "huh!" and beamed at the pool as if it happened by magic and his own sweat.
(I should have let it stay yucky for a few more days, he had agreed to a filter/pump upgrade)
