you can still do it just on a smaller scale fine a 20g tank and you can use the romera in it.just have to make sure the out flow runs down a piece of glass till you get a different skimmer. You could try and sneak it in or just advise her that it would clean up the tank and make it look so much better and people could enjoy it more, or some thing along those lines. My wife new something was up when I made my tank stand about 2 feet longer and 6 inches wider than we needed it for the original tank. I said just in case there is an up grade I don't want to be building another stand and wasting all this good lumber and expensive laminated pine boards that I used for the top.
