Ok. I read I do that via a sock and either in the skimmer basket or tied to an end of a pole or something and dangle it in front of a return jet. Does one way do a better job over the other? Also, what exactly do I use, product wise, to raise the CYA? Is there something preferred over another by most here? And finally, where can I get it? Thanks a million!!!
CYA up to 40 and FC up as well. Keep it at the upper end of the range to give you some wiggle room. The sun ate your FC yesterday.
