So, you just picked up an aquarium, filled it up with some water, got your gravel and decorations looking great, and you’re all set for some fish, right? Well, not quite. If you add a bunch of fish right now, more than likely you will experience a condition that not only is frustrating and discouraging, but possibly expensive. That condition is:
NEW.
TANK.
SYNDROME.
Those are three words that hopefully you only use in conversation when discussing how you avoided it. New Tank Syndrome is caused by a buildup of toxins and an insufficient microbiome to break them down. Sounds complicated, but it’s not.
What it all comes down to is that when fish need to go to the bathroom, well.. they are living in it. Just like you wouldn’t want to go take a dip in a sewage pond on a hot day, fish aren’t exactly thrilled about living in their own p**p. This is where the microbiome and the nitrogen cycle come into play. It’s just a fancy way of saying good bacteria that like to eat fish p**p and other waste and turn it into something that isn’t so toxic. You have good bacteria in your gut that helps you breakdown the food you eat, and your aquarium needs bacteria to help break down what the fish.. well, you know. The problem is that when you set up a new tank, you don’t have these bacteria yet, or at least not enough of them. So when you add fish, the waste can’t be broken down, toxins build up, and before you know it poor Mr. Bubblesworth and friends are taking a one-way trip from the fish bowl to the toilet bowl and possibly going to the fish store looking for one that looks exactly the same (I still miss you, Mr. Bubblesworth-- you were a brave fish).
So, what can you do to prevent this? The easiest way is a process called cycling, which establishes the nitrogen cycle is explained below: [queue the Circle of Life music]
Plant material dies and fish eat food and produce waste->
This produces ammonia (NH3/NH4), extremely toxic to fish->
Good bacteria consume ammonia ->
This produces nitrites (NO2), still quite toxic to fish ->
Good bacteria consume nitrites->
This produces nitrates (NO3), mildly toxic to fish ->
Plants consume nitrates to grow, the rest is removed by regular partial water changes, completing the cycle.
A breakdown in this process at any point, especially the first two, can result in New Tank Syndrome. Since your new aquarium doesn’t have a well-established microbiome of these beneficial bacteria, you need to jump start it. In saltwater aquariums, this generally involves live rock and live sand, which is porous rock containing these types of bacteria (and potentially unwanted hitchhikers). In freshwater, this can be done by obtaining a piece of sponge from the filter of an established aquarium, or the addition of products that contain these bacteria. Keep in mind that using a piece of sponge from another aquarium could introduce unwanted pests or potentially harmful bacteria, so we recommend the use of products manufactured specifically for this purpose instead. Now you need to make a decision—add a fish now, or wait until you established the nitrogen cycle. We recommend you wait as it will be better for the fish and less likely to have a negative outcome. Since there are no fish in this method, there is nothing to produce ammonia, so it must be added. DO NOT USE HOUSEHOLD AMMONIA. Household ammonia can contain additives, such as surfactants and fragrances, that will have devastating consequences. ONLY use ammonia that is specifically labeled for use in aquarium cycling, such as Dr. Tim’s Aquatics or Fritz’s Fishless Fuel, and add it according to the manufacturer’s directions. Then you wait. Yep.. give it time—usually a couple of weeks for freshwater. During this time, be sure to follow the manufacturers directions, which will generally involve testing. You can test the water yourself using one of many available test kits, or you can give us a call so you don’t have to deal with the hassle. As things progress through the nitrogen cycle, you will see things occur in this order after you add ammonia and bacteria:
Ammonia levels drop, nitrite levels increase. ->
Nitrite levels begin to decrease, nitrate levels begin to rise. ->
No ammonia or nitrites detected, only nitrates.
You’re done! Now it is time to find a lovely fish who will enjoy the wonderful home you carefully prepared for it. But don’t add too many! It is best to add one at a time, monitor the nitrogen cycle, and wait until your tank has adjusted to the most recent inhabitant before adding another.
