Aquarium Advice FINatic
So I just picked up a 40 gallon breeder off craigslist. I didn't ask many questions about it because it was brand new. I got home and it says do not fill with water. I'd like to use this for a sump so it would only be 1/2 full. Is it marked critter only because of the silicon used or something? This will be my first epic craigslist fail if I can't use it for the sump
