Keep It at Bay: 11 Ways to Control Algae Growth

Algae is a natural part of the underwater ecosystem. For that reason, some algae growth is beneficial for a fish tank. However, too much algae can create a harmful and unnatural environment for your wildlife. Aquarium owners must take steps to balance and control algae growth, and most of them are relatively easy to do.

1. Don’t overfeed fish.

Overfeeding fish leads to more waste. That creates a generally unhealthy environment in the tank due to the fact that the natural and manmade filtration processes won’t be able to keep up. Such an environment can also make the fish very sick, and plants can suffocate.

2. Include artificial or natural plants in your aquarium, as well as rocks and gravel.

All of these serve as natural filters and control algae growth. They also provide entertainment and shelter for the livestock.

3. Make bottom feeders your favorite.

This is one of the best ways to reduce algae in the fish tank, and also the most fascinating. There are many types of bottom feeders that feed on algae in the tank, acting as another natural filter. Many, such as cherry shrimp and catfish, are very beautiful and entertaining to watch as well. And speaking of filters …

4. Use only reverse osmosis deionized water water in your aquarium.

Other types of water could contain high phosphate and nitrate levels, which could create an environment conducive to algae growth. RODI water, which is 100 percent pure H2O, is also healthier for the livestock overall.

5. Check your filters regularly.

If the amount of algae in your fish tank is out of hand, it’s possible the filters aren’t working as they should. Filters that aren’t functioning properly could also be dangerous to the livestock.

Ways to control algae growth in a fish tank include not overfeeding fish, as well as using proper aquarium filtration systems.

6. Regularly clean plants, rocks, and gravel.

In order for your plants, rocks, and gravel to do their job, you need to give them a hand. Regularly vacuum the gravel. Clean the rocks and plants by removing them from the tank and setting them outside in the sun for a few days. The sun will dry the algae that has collected, and you can then simply rinse them with RODI water before replacing them into the tank. Make sure you have a second set of rocks and plants that you can place in the aquarium while your main set is sunbathing.

7. Change the water regularly and properly.

Do not change all of the water. A small amount of waste is necessary to create an environment that mimics nature, and changing only some of the water ensures that the ideal temperature is maintained. Only change 15-20% of it every two weeks for both reef and freshwater planted tanks, and 20-25% of the water once a month for both fresh and saltwater swim/fish only tanks.

8. Know what types of algae are overpowering your fish tank.

Different types of algae might need different treatments. Ask our aquarium maintenance technician to help you identify the types of algae that are in your fish tank and how to minimize them.

9. Try algae control solutions.

There are many natural ways to control algae growth in fish tanks, but sometimes the ecosystem needs a boost. Brands we prefer for products that reduce algae and clean the tank in general include Brightwell Aquatics and Marineland.

10. Do not place your fish tank in direct sunlight.

Algae make their own food, or energy, from the sun.

11. Use proper lighting.

While most types of fish tanks do need artificial light, minimize the amount of time the light is on. Consider using a light with an automatic timer and dimmer.

Fact vs. Fiction: Why Overfeeding Fish Can Be Harmful

Feeding fish is one of the few times of the day when you can interact with them, so it’s tempting to think of feeding them every time you walk by. It doesn’t help that as soon as you walk by, they’re there at the top of the tank, waiting excitedly, looking at you lovingly. But you are strong, and you resist the urge because you know overfeeding fish can be harmful.

But is that really true? Or are people overstating the dangers associated with overfeeding fish?

What we can tell you is this: It’s probably not what you think.

How Overfeeding Fish Can Be Harmful

Fiction: Fish will gorge themselves if you feed them too much.

Fact: The fish usually know when to stop themselves. In fact, if they don’t eat all that you’ve given them within about five minutes, you’re probably giving them too much. If they do end up eating too much, however, they will produce more waste than the natural filtering processes or the manmade filters can handle, resulting in an unhealthy environment in the fish tank.

Fiction: If the fish are swimming at the top of the tank, it means they’re starving and waiting for me to come to their rescue.

Fact: Not necessarily. They know they might get food and that excites them, but it doesn’t mean they’re actually hungry. Think of it more as they’re simply as happy to see you as you are to see them.

Fiction: The fish won’t eat each other. They’ve lived together this long, after all!

Fact: Sadly, they might. If fish aren’t compatible in a tank, it’s all about the survival of the fittest.

Fiction: Fish food is good forever.

Fact: The flake food loses some of its nutrients about six months after you open the container. Some fish owners say you should use the food within one month. Frozen fish food should be used within about six months.

Fiction: Each and every one of the fish has to eat the food I give them.

Fact: Some fish are in the tank for the purpose of “cleaning” the waste, especially off the bottom. It’s a part of the natural cycle in the fish tank environment and in the wild.

And that brings us to the truths you really need to know about why overfeeding fish can be harmful.

When you feed the fish too much, they won’t eat it all. The leftover food then stays in the tank too long, leading to an unsanitary environment. Additionally, the bottom feeders might eat those leftovers, which means they won’t clean up the waste from the other fish as they are supposed to.

Concerns about Bloat

Why Overfeeding Fish Can Be Harmful

Improperly feeding or overfeeding fish can be harmful also due to the possibility of bloat, a condition that will likely lead to the death of a fish.

Also known as dropsy, bloat is caused by bacterial, viral, protozoal, or parasitical infections. Some bacteria are natural in every fish environment, but too much can be harmful, as noted above. That’s why it’s important to use proper filtration systems and filtered water in the tank to ensure the safest environment for the fish, depending on if it’s a saltwater tank or a freshwater tank.

When a fish is suffering from bloat, it will be clear that it is sick. Its abdominal cavity will fill with fluid, and the fish might lose its appetite, become lethargic, and have visible marks on its body. Other signs include bulging eyes, pale gills, and long, pale feces.

Unfortunately, usually the best solution is to remove that fish from the fish tank and euthanize it.

You can also try to place it in a quarantine tank for treatment if you catch the illness early enough and believe the fish will recover. In that case, you can place one teaspoon of salt per gallon of water into the sick fish’s bowl, and you should treat it with antibiotics and feed it only high-quality foods.
