Okay, I don't know if this is the right place, but I need to find a way to keep my pool clean and mold free. It's just a blow up pool <img alt="" class="inlineimg" src="http://www.mothering.com/discussions/images/smilies/redface.gif" style="border:0px solid;" title="Embarrassment"> by the way. like 5 ft by 10 ft. I don't want to use chlorine and I don't really know anything about salt or if it would even work in a blow up pool. I just don't want the water getting icky and baby getting sick. Plus I can't afford to drain and fill it every day.
