Thanks everyone! I've been researching repairing this on the internet. I also read about puttiing acrylic strips as reinforcements along the inside base which is where it's leaking. I think this is a over my head plus I can barely even move this tank when empty! It seems like it started when I put the last 20 lbs of LR (out of 120)--leaked the next day. Oh well. I'll be cycling the LR for a while anyway.
I just came home from work late and found my 75 g leaking from the front bottom seam. So far, about 1 gallon on the floor. I set it up a week ago. I'll transfer everything over to a 55 g that I have next to it. Does anyone make house calls to repair tanks? Or maybe I should just try to reseal the entire tank myself.
I'm a little disappointed.
About ten years ago, I had a very basic setup with an anemone, clownfish, LR, and hermit crabs. I've been learning a lot--there have been some changes. Nice to meet everyone!
