An aquarium water clarifier is one of those products that may not necessarily be at the top of your list when planning out your aquarium. However, it is important to have in case you need it. After you have set up your aquarium and introduced plants and creatures to the water, the aquarium becomes their new personal space. Like any personal space, it gets dirty over time. Aquariums also get dirty over time from all of the algae blooms, dust, sediment, pieces of uneaten food, gravel dust, and other organic matter. This creates a large group of tiny particles, making the water look cloudy. These particles are so tiny that they can slip through your filter easily. This cloudy look does not help the fish inside and can eventually affect their health, but even more simply, it looks dirty. Keeping your aquarium water looking clean is part of the maintenance of having an aquarium. So in comes the aquarium water clarifier. A nifty bit of chemical convenience that can get rid of cloudy water very quickly.
In this article, you will get the best choices for aquarium water clarifiers while learning about the specifics of water clarifiers and how they can help your tank water look bright and clean.
Some important points to remember is that if you have just cycled your water for a new aquarium, the cloudiness of bacterial bloom is common, and it will go away on its own. There is no need to buy a water clarifier if this is a new tank of water. If you really need to speed up that process, then a UV sterilizer would work best, but naturally, it will take care of itself quickly.
Furthermore, if your tank water is brown and gross due to neglect, aquarium water clarifiers will not help you. You must return to square one and ensure all the equipment is connected correctly.

What to Look for When Buying an Aquarium Water Clarifier?
When looking for aquarium water clarifiers, the first step is to make sure that you are buying the appropriate water clarifier. Some of the brands are better suited for freshwater, while others are meant more for saltwater. Another aspect of aquarium water clarifiers is determining whether it is even needed. As mentioned before, there are some situations where it is not necessary. Knowing if your water is soft or hard would also be good if you think you need it. Softer water tends to require less water clarifier than usual. Be sure to check the conditions of your aquarium before buying or using an aquarium water clarifier.
It is also important to remember that when you add an aquarium water clarifier to your tank, the cloudiness might actually get worse before it gets better. This is a normal part of the clarification process because the tiny particles of matter floating around are starting to ball up into larger particles, making them easier to see. After some time, the larger particles will get swept up by the aquarium filtration. Do not be so quick to blame the water clarifier, as this is a common mistake among new hobbyists.

How does aquarium water clarifier work?
That is understandable if you are still uncertain about how aquarium water clarifiers work. They have a unique way of clearing up your tank. The way it works is that the aquarium water eventually will build up with tiny particles of algae, dust, etc. and become dirty. This build-up of these tiny particles is seen as a cloudy form that takes over the water. Aquarium water clarifiers are a formula that makes these tiny particles stickier. When the particles bump into each other, they begin to create larger and larger forms. Eventually, the larger forms of clumped particles will become large enough that the mechanical filter will be able to catch a hold of them and pull them out of the water. After enough of these larger particles scooped up by the filter, the cloudiness of the water should go away.

Make sure that you have a steady amount of water flow so that the formula can be evenly distributed throughout the tank. Generally, it should not take too long for the cloudiness to go away. Remember that you should use patience when applying any water clarifier. Ensure you read the directions carefully and know how much of the formula you are putting into the tank at a time.
How Often Should I use an Aquarium Water Clarifier?

If you add too much water clarifier, then it can have turn your water a cloudy brown color. That should be harmless and sort itself out after some time has passed.
