Hello everyone. I've been reading up on this site since last year (1st full summer with pool), and it's been very helpful. I opened my pool this past Sunday to find a swamp like many others. Tested water with Taylor K-2006 and came up with the following: FC-0, TA-90, PH-7.0, CYA- Less than 30 (could still see black dot after tube was filled) I raised PH to 7.2, and put enough stabilizer in a sock to raise CYA by 20ppm, and placed in the skimmer. I then began the shock process by raising and holding FC between 15 & 20 ppm. I also added DE to my sand filter as that seemed to help a lot last year. So here is my question: When fighting algae, is it normal to notice the clarity of your water improving faster than the change in color? It's only been 4 days, but I can almost see the bottom of my entire pool, while the color has barely changed. It did go from dark swamp green, to a bright green, but the daily visual improvement has been in clarity and not so much color. Just curious because everyone else seems to see color change from green to grayish white, then start to clear. Thanks!
