Hi,
Been maintaining my own pool for 3 years now, using all the methods on this site. Even over winter I test FC 3 and PH 3 times per week , and TA monthly. Just tested CYA last week for first time in 3 months and it was down to around 30...which explains why my FC dropped from 6 to 1ppm.
Anyway, added CYA and some bleach to get FC back up , last week, and now just playing around with SWG to get the % right based on CYA of 80 now.
So, my pool has always been crystal clear and bright, but I just noticed, the last 3 times I have brushed the sides and floor in last 5 days (I must admit , I went a month without brushing ) , I get a brownish/ greenish dust that comes off the walls and floor. I can even see areas where I missed some brushing (hence doing it 3 times in 5 days ) . My question is, could there be something wrong with my filtration system if I am getting these small brown dirt particles ? Should they not all be washed through and filtered out? Just seems odd , as I presumed that brushing it all up would make it goes through the filter system.
thx
