What is New Tank Syndrome?

If you recently added an aquarium on your own or are doing research into the topic, you may have come across this term. It’s often vague and confusing and is most commonly used to sell some sort of aquarium “treatment.” Symptoms of “new tank syndrome” include milky or cloudy water, and sudden fish loss. The thing about new tank syndrome is that there is no such thing. The above conditions are indicators of a chemical process that happens in ALL NEW FSH TANKS. In fact the process (called cycling) is so common it is probably happening in your glass of water or the water in your toilet right now. This is an overly simplified explanation of cycling but essentially what’s happening is as follows.

Clean, new water is added to your tank. Most commonly tap water or filtered bulk water. This water has a very low amount of a certain group of beneficial bacteria. These bacteria “eat” ammonia and toxic waste produced by living organisms. As soon as fish are introduced to the tank they begin to produce theses waste chemicals in large quantities. The small amount of bacteria in the water can’t keep up and the water quickly becomes polluted with the excess toxic waste. (Within 3-5 days usually) This is when fish loss occurs. The levels of ammonia and nitrite in the water are so high that the water cannot support life. Luckily the bacteria love this. They start eating all the toxic waste and reproducing. Their numbers explode and they set up permanent shop in the gravel bed, filter material, anywhere they can grab on and still contact the water. At times, the amount of bacteria in the water is so great it can be viewed with the naked eye. The white milky or cloudy haze commonly described is actually the bacteria holding on to each other to try and establish a permanent residence.

In time excess bacteria die off and the tank is left with a very powerful biological filter capable of processing toxic fish waste as quickly as its produced. This process takes about 4-6 weeks on its own. It CAN be sped up by adding a larger number of living bacteria at the beginning. The problem is, although very hardy these bacteria do need to be kept alive. Most products available to the public have at best very low live bacteria count and contain mostly de-chlorinator. Importing live bacteria into a new tank is possible, but better left in the hands of professionals.

Client Reviews

"Great people to work with. Glad I was able to finally find a solution for my Sunroom!"
"Eric has been nothing but professional! I have been working with him for about a month now and he has been extremely patient with us and I want to make sure that we get exactly what we want. He has sent me several ideas and been working with us every step of the way. We are looking at a March/April install and looking forward to it. I would highly recommend them!"
"They were punctual, friendly, professional, and very qualified. I really can't say enough good things about this service and I highly highly recommend them."
"Eric, the owner of The Fish Guy, called back immediately and even though it was a Saturday and it was snowing, he came over prepared to repair the leak which involved a PVC pipe and joint under the aquarium. He covered the floor completely to protect it, and then cut out the leaking PVC, and replaced it. Working under an aquarium in a confined space is not easy, but he completed the work in a professional and efficient manner. I am very grateful to him for coming out on a Saturday, and not trying to take advantage of the situation."
