Fish/Leaking tank?


Hi richard.
I don't know if you can help but I hope you could! I discovered last friday after cleaning my fish tank ( I did about a 75% change out if that matters) . the next day I notice water around one of the back legs to my fish tank stand and follow the path up to, the fish tank! Ahhhh no. While I have had aquariums for many years now, this is the first ive ever come across this problem. It is a leak, not a crack in the glass ( thank god), but it has been having a steady and slow leak for a week before I was able to get the scillicone repair . I have had to refill the tank twice to replace the water lost, which has been about 6 gallons. I can't be sure if that is all lost from the leak or if evaporation as it has been warmer for the time of year here the last few days. I need sort of a step by step plan for how to tackle this as i've never had this before and i've looked how to repair a leak on the web but it seems like they expect it to be done in a day but i've read you need to take like a week to do this right, so....what should I do? It's a 55 gallon tank and I have just 5 fish in it that I already have containers put aside for them to go in. Thanks a bunch  if you can help :)

Hi Lauren

I've only had one tank in my life that leaked and it was under warranty so I exchanged it for a new tank. I don't have any experience in repairing leaks in tanks.

Most aquarium manufacturers offer 5-10 year warranty, and some even come with a lifetime warranty. So if you can locate your original sales receipt, you may be able to get it replaced.

Sorry I couldn't be of further assistance, good luck!

I own and maintain several freshwater aquariums from 2 to 180 gallon. I can answer most questions about freshwater aquariums, including setup, cycling, maintenance, compatible tank mates, feeding. Moving? I've moved fish both across town and across the country and can help you get your little aquatic friends to their new home safely. I know and have experience with most freshwater community fish, South American Cichlids and African Cichlids. I don't answer questions about Goldfish or keeping Goldfish with Tropical Fish. I also don't answer questions about keeping crustaceans (shrimp, snails, crabs etc) with Tropical Fish, nor questions about saltwater fish or aquariums. I'm not available to answer questions on weekends, this is when I do maintenance on my own tanks.
