[quote]Moon's gravity pulls on the ocean and makes waves[/quote] Teh puma might be wrong on this, but last time he checked... tides and waves were still two different things. Usually to get waves you need some form of seismic activity, or the more common option, wind. To get wind, you'll need changes in air pressure. Since people typically don't have swimming pools half the size of Florida, you will not notice these air pressure changes.
