Cloudy Aquarium Water - how to fix it!

White cloud aquarium water is a bacterial bloom. Something has caused your tank to be out of equilibrium with your bacterial colonies versus your ammonia production. And your bacterial colonies are trying to multiply rapidly to re-establish that equilibrium.

In this article, we'll talk about how the aquarium can be thrown out of equilibrium and how we can fix that.

New Cycle 

In a new cycle, whether with fish-in or fishless, the bacterial colonies grow, which results in a bacterial bloom when the tank is newly established. Right now, the bacteria is colonizing and in the water colonies, so it looks white and cloudy. Once it reaches that equilibrium, it will settle on the surface, clearing your water.

That's how a cycle works. 

Once your aquarium is established, bacterial bloom can happen by adding new fish or increasing your load. Adding fresh fish will increase your fish load. Or you may be feeding more than required. 

Your bio load results from all the ammonia and waste being introduced into the tank. Anytime you increase your bio load, your bacteria, if it's a large enough bloom, you will get a bacterial bloom in your water. Eventually, it will go away. 

Water Changes

Water changes in and of itself do not remove bacteria. However, when you do significant, slow water changes and the surfaces in your aquarium are exposed to the air and allowed to dry out, you can experience bacterial die-off. 

Losing enough bacteria could result in a bloom, which can help you kill the flower. If you turn your filter off or experience a power outage or your filter fails, you can have bacteria die off from there.

If you do a lot of gravel cleaning or filter changes, you can experience a significant loss of bacterial colonies, and you'll get a bacteria bloom from that. Or if you keep changing the filter of your filter cartridge system on a hang-on back filter.

How to deal with bacterial bloom

The fish thing is to ensure you have some test kit. You have to use this test kit of ammonia and nitrite spikes. 

Since your tank is out of equilibrium and your bacterial colonies are offset, you want to make sure you are not getting any large ammonia or nitrite spikes. 

You can use a detoxifier if you are getting ammonia or nitrite spikes. You can also add a bacterial additive if you want. But it is not a requirement.

As long as you are monitoring your ammonia and nitrite, dosing detoxifier will help re-establish that aquarium, and you'll again have crystal clear water. 

So, please have patience and monitor your parameters, and the tank will re-establish itself.
