The Top Tips On How To Cycle A Fish Tank With Goldfish

Last Updated on April 29, 2022 by

Are you interested in learning how to cycle a fish tank with goldfish? We have compiled the best information on what you should know in this article.  

Cycling a fish tank is a necessary task for every owner. It is basically controlling your tank’s water to go through the nitrogen cycle so you can clear the tank from harmful nitrites and ammonium.  This can be done in a number of ways.  

Typically this needs to be done prior to putting your fish in a brand new tank. However, it is possible to cycle your tank with the fish still inside the tank. Cycling establishes the proper bacteria in your tank that will eat nitrites and ammonia and changes them to harmless nitrates.  

Every fish has different needs.  But overall, the cycling process is the same for most fish.  That being said, we have created an article that is about specifically how to cycle a fish tank with goldfish.  

Goldfish are some of the most commonly raised fish in the U.S.A.They are raised for their attractive orange color.  In fact, according to the University of Washington, “If a goldfish in the wild is anything other than bronze/gold/orange, they could easily have originated directly from a local hobbyist’s aquarium, as after a few generations, the goldfish will revert back to its wild type.”

What Are The Steps To Cycle My Goldfish Tank?

First off you need to find your fish tank.  Keep in mind that goldfish are 1-2 inches on average. Make sure that you have a big enough tank to hold the amount of goldfish you want to raise.  

Always keep in mind the “one-inch per gallon” rule.  This means that for every inch of fish, you should allow one gallon of water.

If your tank is overcrowded you will have serious ammonia issues.  Once you have your tank established you have to set up your tank as you want it to be for your fish.  This means adding your tank substrate, plants, filters, pumps, and any decorations you want to add.

Next, add the water.  Always keep in mind the water source which you use to fill up your tank.  Some city water adds chemicals like fluoride and chlorine to the water.  

If your tap water has chlorine in it, let it sit in an open-aired bucket for 24 hours.  This allows for all the chlorine to evaporate and makes the water safe for use.  

Once your tank is filled with all its content, it is time for you to start cycling.  All you have to do to start this process is beginning to pump your tank water through the filter.  

Basically, you have to keep moving water through your filter for beneficial bacteria to build up.  The beneficial bacteria established in cycling will cling to the filter.  Once it is established it will work to digest harmful ammonia and nitrites that appear in your tank.

What Amount Of Time Should I Cycle My Goldfish Tank?

That is the basic way how to cycle a fish tank with goldfish.  Doing this process can take a while, though.  Some tanks tank between 1-2 months to fully become ready for fish.  

However, there are ways to speed up this timeframe.  

One way to accelerate the natural process is to add small amounts of ammonia to the water.  As you do this, bacteria will appear that like to eat ammonia.  

If you are going to choose this method, you should buy an ammonia test kit so you can monitor the ammonia levels in your tank.  This way you can measure if there is a sufficient amount of bacteria established in your filter.  

A second way to accelerate the cycling process is to use heat.  Beneficial bacterias grow faster in warmer environments.  You can use a water heater in your tank to raise the temperature a few degrees.

Once you feel confident that your filter is strong enough to do a good job, you can add your fish.  Always keep in mind that nothing is guaranteed.  Monitor your tank’s water chemistry frequently in the first months of your tank.
