Hello FishLore! :;hi1 This morning I woke up to a soaked floor around the perimeter of my fish tank. :/ I checked the tank for leaks, before setting it up, but somehow somewhere, it has a leak! I'm not gonna go out and waste my money on sealants, I'd rather just go out and buy a new one, because I bought this one second hand. My main problem is that I've got a filter here, that is for up to 30 gallons. My tank was a 15 gallon tall. So what should I be looking for? And my glass lid is a 10" by 20". By the way, I'm not worried about the fish, because I never got to the point of buying fish, yet.
