This is the third summer with a new Marquis finish on my pool. It's been a nightmare keeping the chemicals balanced and this summer is the first summer that the water is sparkling. However, I'm having to hose off the filter at least twice a week and I get a lot of sand out of it. A couple days ago I noticed blue flecks in the sand...what is that all about??? If anyone has any opinion I'd appreciate hearing it!
Thanks!
ps...I'm in Florida if that makes any difference.
