Amazing board!! You have saved me hundreds of $$$ and it was so easy after the first few weeks. Now, what can I do with these stupid tri-chlor pucks? I bought them before Pool School and haven't used them mainly due to my CYA being pretty high all season. In the 90's then 70's and now about 60. Should I throw them into a floater when I close the pool this week or throw them out? I plan on starting the shock tonight for a Thursday close.
