However, algae growth is a normal part of having an aquarium. It is something that every fish owner has to deal with at one point or another. When it comes to how to clean fish tank ornaments from algae, thankfully the process is quite simple.

How To Clean Fish Tank Ornaments From Algae
As long as you follow the steps which we have outlined below, you should have no problem getting rid all of the algae on your fish tank ornaments. The process is fairly simple.
Stopping Algae From Growing Back
Besides removing all of the algae from the rocks and decorations in your aquarium, there are also some steps that you can follow to ensure that this algae does not come back with a vengeance.
Follow the tips outlined below to prevent algae from growing on your ornaments.
- Aquarium Lights: Light is a big source of energy and life for algae. Depending on how much light your fish and plants need, this can be a problem. However, a good way to ensure that algae does not grow back, at least not too quickly, is to leave the aquarium lights off for at least 16 hours per day. Without a good light source, algae has a really hard time blooming.
- Fluorescent Bulbs: If you use VHO or fluorescent light bulbs, you will want to change them every six months at the least. As these kinds of light bulbs get older and degrade, the wavelength of light that they give off changes. These changes in light wavelengths are often a big cause of algae growth.
- Replace Water: Make sure that you replace around 15% to 30% of the water on a weekly basis (more on water changes here). This will help remove algae spores and particles from the water. Algae can multiply very quickly, so this is fairly important.
- Skimmer/Filter: Look over your protein skimmer and your filter at least once per week. An effective and well-functioning filter and protein skimmer can make a big difference in terms of keeping algae at bay. Also, the filter removes fish waste from the water, fish waste which produces ammonia, ammonia which causes algae to grow.
- Water Tests: You should perform weekly tests on the water in your aquarium for things like ammonia and nitrite. Algae grow really well when there is a lot of ammonia and nitrite in the water. Testing for these substances will help you determine the problem and will help you find the right solution.
- Tank Cleaning: Cleaning your aquarium on a regular basis will help stop the algae from growing back as well. Removing uneaten food, fish waste, and any other source of contamination is key. Algae feed on all kinds of things, so having a clean tank is a great way to stop it from growing.
- Remove Dead: Always make sure to remove any dead fish, plants, or other dead creatures from the water. They give off ammonia which algae love feeding on.
Cleaning algae off decorations is definitely not very hard, but making sure that it does not grow in the first place can be a little tricky. However, if you follow the steps and tips outlined above, you should be able to deal with algae growth with no problem.
