Brown algae come in olive green or brown depending on the dominance of the pigment in their body. They vary in size and this ranges from a small seaweed to a large complex size. They are commonly found in new tanks or aquariums. To know if your tank is having brown algae, gently rub your finger on the glass, if you notice any soft slimy thing, say hello to your new friends. Frankly, they have always been in the water, they just need the right environment to grow. Moreover, these creatures cannot swim, they only cling tightly to the aquarium glass, decorations, plants or any stable surface in the aquarium.Most people confuse brown algae and diatoms due to the fact that they can both thrive under sunlight and they can be a pain in the neck when it comes to eradicating. However, diatoms consume silicates to grow while algae do not. Also, another problem fish owners encounter with diatoms it that no matter the number of times the light is off, diatoms will still survive in the diatom aquarium. Moreover, when you think you have succeeded in eradicating some amount of nitrates in the water this stubborn creature will still live on silicates.
Causes of brown algaeBrown algae in fish tank, How? Well, there are various factors contributing to the development of this annoying thing in your fish tank. Understanding the causes will help you to take necessary steps in combating the problem.
High Level Of Silicates:
Excess silicates in the water is a bonus for the diatoms. They will consume the silicates and just die but the thing is this might take months.
- Using tap water that is high in silicates acid is one way to increase the number of silicates in the water.
- Introducing of sand-like play sand or pool sand to the substrate will increase the silicate in the fish tank.
- Using salt mix will spike up the silicates in the water. Read the label and ensure the salt mix does not contain silica before using them.
High Level Of Nitrates In The Water:
Nitrates are part of the nitrogen cycle and nitrates build-up occur when you fail to constantly change the water in the fish tank. Not only does high nitrates charge up brown algae, but it is also harmful to your pets as it weakens the immune system. Other things that can increase the level of nitrate include
- Overpopulated habitat.
- Decayed material and food, fish poop are also sources of nitrates.
- Plant fertilizers consist of high concentrations of nitrogen. Be careful when you are introducing them into the fish tank.
Inadequate Exposure Of Diatom Aquarium To Light:
Inadequate exposure of your fish tank to the lighting can cause an algae bloom. Unlike the green algae, brown algae thrive in dim light. A light timer will be of great help to ensure that your fish are getting enough light.
High level of phosphate:
All living creatures depend on phosphate for survival and there is no way you will want to get rid of them if you want a successful fish breeding.
The bad news is a high level of phosphate can lead to the bloom of algae and diatoms in the fish tankThis happens as a result of the presence of uneaten food, dead plants, dead fish and fish feces. Ensure your tap water is tested to know the amount of phosphate present in it.
How to get rid of brown algae( Diatoms)The application of these methods or steps is a good solution and will answer your question on how to get rid of brown algae.
- water can be removed and replaced with clean tested water. Use reverse osmosis or deionized water to replace the water in the tank. These techniques ensure there you are not adding to the supplements that are favorable for the growth of algae.
using vacuumVacuuming of the gravel is also a good way of removing brown algae that are on the gravel. You can use a siphon to vacuum the gravel or any other aquarium decor present in the tank.

Are they compatible with my fish? Will the habitat be crowded if I get them? Will they find these fish friends or food? These are the questions you can ask yourself before introducing critters into your aquarium.
Each time you are adding the salt mix to your aquarium, ensure they are silicate free as you don’t want to contribute to the growth of the brown algae in your fish tank. Moreover, adding live sand or live rock is like laying a welcoming rug for an algae bloom.One effective way to reduce silicon and phosphate is to use phosphate adsorption resin in the filter to ensure a silicate free water in the aquarium.
Supplying appropriate lighting for your pet is one thing you can do to eliminate brown algae. Eight hours’ exposure to lighting per day is okay, however, if you don't have any other live plant in the fish tank, you can reduce it to six hours.One good way to balance the lightning is to fix an ultraviolet sterilizer that will act as normal sunlight. They have no side effects on the fish but will rather kill any bacteria or brown algae that might be present in the fish tank.
