Does anyone have a link or access to a DIY tank similar to the ones that Petsmart has with their aquaric plants in it? The one that is square (really 4 tanks in a square) and cascades from the highest to the lowest? I'd really like to make a version of that, but I can't find a good place to begin...
Also, would each 1/4 tank have to have it's own filter?? Or would the overflowing water be enough??
