Oh yeah forgot to add

Thanks for the compliment Bill. I actually really liked a it and so did my little froggies. Although being a flexable material underneath and grout on the outside I found that 1 drop was all it needed to completely destroy it. I will probably build another one later but for the time being I just bought the premanufactured Tetrafauna one to get my little guys a waterfall back. I am currently working on getting my Tincs out of their little 1 bed apartment and into a nice spacious penthouse suite! As soon as that build is done then I will have time to play.
