my friend came over the other day and we was talking about pools and i showed him mine and he said he had never seen a pool so crystal clear and i told him about this site and told him i would help him clean his green swamp and he agreed to listen and follow my instructions. well i went out to his house and this is what i found
well i did a full set of tests and these were the results
cya-all the way to the top and could still see the dot.
i did not know if there maybe below 20 ppm so i told him to add enough to bring it up to 30 ppm so we would not over shoot our goal of 45 to 50.
and i told him to go buy a whole lot of bleach and he did....lol.
started the next morning dosing it up to 15 ppm fc per cya/chlorine chart.
and had him brush the pool and vacuum it as often as possible, and i told him he needed to take out the walk in steps because the algae would be hiding under and behind them, but he did not want to. this pool is a 33 foot round by 52 inches deep and he has a cartridge filter.
