Alright, I'll soon be taking down my 44 gal pentagon tank. At first I was just going to toss it since the top few inches of glass is stained/scratched. But then I though, hey it fits perfect where it is, why not make it a frag tank. It's too tall I told myself. Well then, cut it, myself told I. So heres what im thinking. The tank is 25" tall, way to high for a frag tank, and the silicon need resealing real soon. I want to take apart the tank, remove all silicon and cut the glass down to between 12"-18"(have not decided yet), then put it all back together. Drill it, add a small sump and presto a nice frag tank. My problem is I know nothing about replacing silicon in an aquarium and even less about cutting the glass down. Am I crazy for doing this? Any tips? Suggestions? Everyone add your 2 cents. In case you dont know what shape this tank is here is a pic. Thanks in advance.
