WOW!!! That again is awesome. I gotta take my girls down there. It seems to be unbelievably cool!!! Yeah I figured that it would be a bit difficult to do. Also I have no idea where to get one. I have been thinking of doind the 100 galon rubbermaid sump/fuge with some partitions in it to keep things all separated and thought it would be cool to have one of those in the sand chamber. We'll have to see how it all plays out. Any ideas of a vendor or individual that would have access to them. I imagine that someone in Fla would be able to get them fairly easily???? Thanks for the pix again!!!! They are awesome. Did you take those on your tour??
