I had a couple of crashes when I was first starting out, the first one was due to adding addtional fish without qt'ing first, the second was when i used a sponge to clean my tank that was not supposed to have any antibacterial on it, but later when I called the company they said it gets done on the same assembly line as the antibacterial ones, and is not aquarium safe (would have been good to know that beforehand). Both crashes had me really ****ed off with each one costing me more money wise, but I learned about patience and got right back into it.

Full crash would allow me to upgrade tank and i already have a second frag tank to help stock it back up .
