I finally got the Taylor-K2006 a few weeks ago and have been testing the chlorine mainly because I cant understand why i keep havin algea bloom. This is what happens. My water turns greenish, I raise the FC level for 3 to 5 days (between 7 to 10), then i turn off the pump for 2 to 3 days, the green settles to the bottom, since I cant get it to filter out thru my sand filter I have learned to vacuum using the 5 gallon bucket of water outside the pool. (this vacuums with a softer suction and doesnt swirl the algea as quickly from the bottom plus doesnt waste as much water) Everything gets to lookin good, then a few days later, its greenish again! Today the pool turned greenish and the FC was 7. It had been 9 two days ago. I didnt think that was very much of a chlorine drop if algea was present. So here is a complete test. Please advise me.

FC= 7
CC=0 (a few days ago the water turned a pale pale pink after 5 drops of R-oo3, today it stayed clear)
PH= 7.0
Alkalinity test (water was no longer green at 70, hot pink at 80, actual red at 100) so Im guessing 90-100?
CYA= dot started disappearing halfway between 40 and 30, so 35? I added a little more and it really disappeared, it wasnt quite to the 30 mark...so 32?
