Let me first start by saying, I have been using Bleach to chlorine my pool since start up since March 2013. Having great results.
FC: 3 - 5
CSI: 0 - .03
POOL TEMP: avg.88
AIR TEMP: avg.95
My PB left me with a bucket of Chlorine Pucks (never used them), Since my CYA is close to the low side I thought I would try it. Well, I start using the pucks yesterday (sat.).
My pump runs for 8 hrs a day 1100 - 1900, 5hrs low speed 1100-1600, 3hrs high speed 1600-1900.
1630 - FC: 2.5 CYA: 35
1700 - installed 7 pucks in cylinder, turn dial to setting #4
1300 - FC: 1.5, turn dial to setting #4.5 (pump running on low speed)
1600 - FC: 1.5 (pump just started on high speed)
1900 - FC: 2.0, turn dial to max setting #5 (pump finished on high speed)
Since pump shuts off at 1900, no since checking FC after 1900 when pump is not running.
Will check tomorrow on FC results, and check this weekend for CYA level. The pucks doesn't look like its going to keep my FC high enough for my likings And I wonder what my CYA level going to be this weekend? I check FC/PH everyday, and check CC/TA/CH/CYA every weekend.
Anyone having good luck with FC & CYA using the pucks, or should I sale them in a garage sale?
