Is there a limit to how much live rock can be added to a tank? I got a tank back in Nov 2009 and everything has been fine up until this morning, woke up with water everywhere. Well apparently the leak was at the front bottom of the tank where the seal is, couldn’t pinpoint exactly. I don't know if it was just a coincidence or what but I just added about 20 pounds of rock Saturday afternoon. So I broke everything apart and took it back to my local store for them to replace the tank. I have right at 145 pounds of live rock with 80 pounds of sand and I was curious if I had too much live rock and sand in the tank that it put too much pressure on the seals or something.
