Cool little tank and intank sump filter idea

SO I am in the process of making a rack for a few tanks to breed some convicts for feeders and I did not have enogh filters to go around that were the right turn over rate for each tank. So I took my little pump out of a repto filter that pushes 120gph and made a intank sump sort of filter. I also made the tank out of some glass shelving. The pump is in the bottom of the filter and then it has scrubbies and then some filter floss on top. I was going to make a drip plate but this serves its purpose for now. Let me know what you think. This one has worked so good that i am now making one for the 29g as well with a power head for the pump in the filter.

Thanks alot ---i was worried about the shelves cause they have beveled edges and rounded corners so thats why I went so thick on the silicone. The bevel was about 1/2'' in length and took the glass thickness from 1/4'' down to allmost 1/8''. And the corner had about a 1/4'' radius on them. But it has been up and full for 2 weeks now and no leaks yet so I guess were good.
