Cloudy Fish Tanks- What Every Aquarium Hobbyist Should Know Featured

Before you can treat the cloudy water in your fish tank, the best thing to do is to analyze the cause, which can be one of several things.

Cloudy fish tank water is one of the most common problems affecting novice and experienced aquarium hobbyists alike. This problem is not only common but it can also pop up unexpectedly – one day your tank could be perfectly clear and the next day it might look like you poured a cup of milk into the tank. Before you can remedy your tank’s problems with cloudy water, you need to learn the causes of this condition and explore the treatment options available.

Causes for Cloudy Fish Tank Water

Before you consider some of the more serious causes for cloudy tank water, you may want to check to be sure that it isn’t the result of something as simple as dirty substrate. If you do not thoroughly rinse your aquarium substrate before adding it to your tank it could not only introduce harmful contaminants into your tank but it could also cloud your tank water. Another possible cause for cloudy tank water is a bacterial bloom. When a sudden growth of bacteria results in a cloudy appearance in aquarium water, it is generally referred to as a bacterial bloom. These growths can occur suddenly and may be brought about by a variety of factors. If your tank has not cycled properly or if there is a significant accumulation of waste build-up in your substrate, your tank is likely to experience a bacterial bloom. In some cases, algae blooms can also cause cloudy tank water but these blooms generally turn the water green rather than milky white. Algae blooms are generally caused by excess lighting or carbon dioxide so controlling these elements in your tank will help to prevent an algae bloom.

Recommended Solutions

Many aquarium hobbyists assume that cloudy tank water can be remedied by replacing a large quantity of tank water. While removing the cloudy water from the tank might seem like a good idea, it may not solve the problem. Before you can solve your tank’s problems with cloudy water you need to determine its cause. Performing an aquarium water test should help you determine whether there is a chemical imbalance in your tank and, if there is, you will have a good idea what you need to do to fix it. High ammonia levels may indicate that your tank has not properly cycled or that organic waste is building up in the bottom of your tank. The simplest solution in either of these cases is to siphon your tank substrate, removing the accumulated debris. Once you have removed the accumulated debris you can replace the water you removed with fresh dechlorinated tap water. It may take a day or two for your tank to return to normal but, in most cases, this solution is sufficient to remedy problems with cloudy tank water.

Additional Tips and Tricks

If you want to ensure that your tank water stays clean and clear, think about adding an EcoBio-Stone to your freshwater tank. EcoBio-Stones are made from porous volcanic cement and they are infused with the beneficial bacteria your tank needs to maintain the nitrogen cycle. Once these bacteria are introduced into your tank, they will multiply and get to work breaking down waste products and eliminating harmful toxins like ammonia from your tank. Replacing your filter media once a month and testing your tank water on a weekly basis will also help to prevent a recurrence of cloudy tank water.
