I bought a ~30 gallon aquarium and got it fitted for a glass lid, intended on using it as another step up when my Neps outgrew their current space. Unfortunately, I accidentally cracked the bottom pretty badly, badly enough that the glass has to be replaced. I went to the local glass store, which told me that the glass would be pretty cheap (I'm guessing on the order of $20, but idk for sure), but, to replace the bottom would be about $100 because they'd have to cut the silicone, get special marine silicone, etc. As a consequence, they recommended I just buy a new tank on Craigslist.
I wondered if anyone had any experience replacing the bottom of an aquarium themself, and had advice about whether to pursue this possibility or not. For reference, 55 gallon aquariums go for about $50 in my location on Craigslist.
Thanks for the help,
