Water Green in Fish Tank

Having a beautiful fish tank is a thing of joy but sometimes keeping the water looking and smelling clean and healthy can be a problem. And this has proved to be troublesome for some beginners because it can be hard to figure out what's going on.

The reason you want to keep your water clean and clear is because if it is not, it can prove to be disastrous for your fish and other creatures in your tank.

Over the course of the next two posts I will outline 2 common problems that you will probably encounter in regards to your tank water. We will talk about green water and cloudy water. In this first post, we will discuss green water.

Water Green in Fish Tank
If your tank water is starting to get a green hue to it then your tank is probably starting to be infested with algae. It definitely is algae if there is a green buildup on the sides of your tank walls. This is a common problem and it can take over your tank very quickly.

You may be asking yourself, 'what causes green water?' Green water in your fish tank oftentimes is caused from overexposure to light, especially sunlight. Keep your fish tank away from any sunlight that may be coming in via a window. You may have to physically move your tank away from a window.

You can eliminate green water in your fish tank by using an aquarium UV sterilizer. You can run one for a while and it will gradually eliminate the algae in your water. Once it is gone, then you can remove the sterilizer.

Another option is rub down the tank walls to remove the green algae buildup and then do a number of small water changes over a few weeks. Don't do a big water change because you could end up disrupting your essential bacteria.

Try these techniques along with reducing light exposure to your tank and in time you will conquer the green water in your aquarium. In my next post, I will focus on curing cloudy water in aquariums.
