How To Control Nuisance Algae In The Saltwater Aquarium

As you can see, algae control on marine aquariums is closely related to water quality and proper tank maintenance. There is no need to use water clarifiers or other chemical substances that will hide the algae problem in your tank but not fix it. You can get rid of algae on saltwater tanks by making sure the conditions for algae growth are not in your aquarium, and encouraging the growth of beneficial macro algae instead.

Let’s take a look at a few of the pros and cons of coralline algae in a saltwater aquarium:

Algae thrive when there are plenty of nutrients in the aquarium water. However, when nutrients are in short supply algae growth slows down. Nitrate and phosphate are the two nutrients that we can easily limit in saltwater aquariums. Nutrients enter the aquarium in tap water and through fish and invertebrate foods. If your tap water contains nitrate or phosphate, every water change or top-off feeds the algae! A (RO) filter system will remove phosphates, nitrates and other unnecessary nutrients from the water supply and keep them out of your aquarium. Fish and invertebrate food contains the essential vitamins, minerals and amino acids necessary to sustain corals, fish, and other marine life. It is also a source of nutrients that stimulate algae growth. Feed small amounts of food so none gets sucked into the filter or trapped behind the rocks. Many aquarists have found that fish don’t need a lot of food to remain healthy and colorful. The same goes for corals. Any food that is not needed simply adds nutrients to the water. Try feeding less food and watch the algae disappear!
