Looking around online for winterizing stuff (antifreeze, poly60, etc.) for my first attempt at pool closing (builder closed 1st year, and we paid em the 2nd) I stumbled across this:
http://www.intheswim.com/shopping/produ ... word=E9NAC
It claims to be a non-chlorine based oxidizer but doesn't really say what it is. Lots of good reviews on it, but that doesn't always mean much.
Does anyone know:
a) What it really is? I have a guess but don't want to provide a leading answer (and it's *just* a guess)
b) Does it work / is it a valid option or should I avoid it like the plague?
(Note that there is some "chemistry curiosity" involved in my question as well as practical application for closing the pool)
On a slightly different note, we'll probably close around early Nov. and open around end of April - does the recommended (on this forum) dose of poly60 for winterizing really "hold out" over the entire winter or do you "check" at spring thaw or something? I know the algae slows/stops as it gets cold but... (I lack confidence )
Final question (for now) - Is there really anything I need to know/avoid in closing because of our dark plaster surface?
