Can I use the sanitizer to introduce stabilizer into the pool? I have read where placing the product in a sock and placing that in the skimmer is a good method, but I wasn't sure if i could just use the sanitizer (esp since I'm not using chlorine tabs).
Also, how important is calcium hardness? My pool is has a vinyl liner and I'm not interested in throwing money away on something that just isn't needed.
Thanks for your help!
