Ok, so another neighbour had asked me to take a look at his SWG pool based on the other neighbours chatting.....
this guy has black algae spots in corners of the steps and in the grout of the tiles.
He had replaced his salt cell back in January.
today's reading were:
FC 2.5
CC 0
CH 500
TA 70
CYA <20
pH 7.8
salt 2500
He says that his cartridge filter is mucky green last time he cleaned it. The water looks clear and blue and his salt cell is at 100%.
So, he knows to get the pH down to 7.5 and to get the salt up to 4000ppm for his machine. He can't remember the last time he added CYA but he thinks it was in January when he replaced the salt cell and Leslie's tested the water for him.
Does he need to SLAM? What about the black algae - should this be dealt with before or after the SLAM? Adding CYA? Should we test the water like I did with the other neighbour's at 10ppm for 10 minutes and then when it's holding add the CYA?
Why do I think the pool stores around here are sooooo bad???
thanks
