Different Types of Foam
Water Agitation
When filling up or refilling an aquarium, water tends to move around. It gets agitated, leading to bubbles or foam forming on top of the water’s surface. This type is the most harmless type of foam and will disappear after a short time. To prevent this, you need to pour water by tilting the tank or pouring water on the tank’s side to prevent foam.
Cleansing Foam
This is quite a fatal form of foam, and you should take care of it. Foam can form due to soap or cleaners. Suppose you use household sponges or buckets or any other type of equipment to clean your tank. In that case, there is a chance that residue can stay behind in the tank and cause the formation of foam on top of the surface.
That is why you should ensure that you keep your aquarium cleaning supplies separate from any other sort of cleaning for your household. Even a small amount of cleaning residue can kill your fish.
Protein Foam
If there is excess protein in your fish tank, that can become a reason for foam appearing in it. Protein can form because of two major reasons. The first reason is that the build-up of debris in your filter can cause protein build-up. The other reason is decomposing fish, waste, and decaying fish food, causing protein build-up.
Protein coats the bubbles present in the tank. This leads to visible foam on top of the fish tank’s surface. To prevent this, you should keep your filters well maintained and clean. If there are any dead fish, you should promptly discard them.
Aquarium Plants Pearling
If you have any live plants or corals, then you might know that they carry out the process of photosynthesis. During this process, bubbles form on the leaves and surfaces of the plants. This is a perfectly healthy behavior, and you shouldn’t be worried if this happens. In fact, you should worry if this “isn’t” happening.
Lack of Air
If you notice that your fish are swimming to the surface and releasing bubbles and foam starts to form, you should take action as soon as possible. This is because this is an indication that oxygen levels in the fish tank are below standard. You should provide a separate oxygen source by adding things such as streams and a bubble machine in your tank. Otherwise, your fish might die due to a lack of oxygen.
Conclusion
Keeping your fish healthy and happy should be your number one priority. If you find out what type of foam is forming in your tank with this guide’s help, you should take appropriate action as soon as possible. But one thing to note is that most well-kept fish will let out oxygen in the form of bubbles. Hence, there is no need to worry if that is the case, as your pets are safe and sound.
