I was thinking that we'll get some "shocking" treatment for the pool for if it starts to get out of hand. Hopefully that will get it back under control. I know it's in the water when we swim, BUT, I think it will be an all around good experiment too! :-) Yeah, I think the peroxide would get a LITTLE spendy- YIKES! LOL I know it won't help with the oils, etc. but it does have a filter, so hopefully that will help a little- I'm just hoping that the CS is small enough particles to pass through the filter, and go back into the water!:-0 Thanks for your input! It's much appreciated!!
