Food Source for Fish and Invertebrates

Many fish and invertebrates, such as Otocinclus and Axolotls, feed on algae as part of their natural diet. Algae wafers are a popular choice for supplementing the diet of herbivorous fish and invertebrates. Even dogs and cats may benefit from nutrients found in algae.

Nutrient Control and Oxygen Production

Algae help maintain water quality by absorbing excess nutrients such as nitrates, ammonia, and phosphates. By consuming these nutrients, algae keep them from reaching levels that would be harmful to fish and other aquatic life. Additionally, through photosynthesis, algae produce oxygen for your aquarium inhabitants.

Dealing with Excessive Algae Growth

Causes of Excessive Algae Growth

Excessive algae growth can occur for various reasons, including inadequate lighting, overfeeding, and imbalanced water chemistry. For example, hard water and high nitrate levels can encourage algae growth, while blue light may also boost their proliferation.

Preventing and Controlling Algae Growth

Here are some practical tips to prevent and control algae growth in your aquarium:

  1. Limit nutrient sources by avoiding overfeeding and using a suitable aquarium filter.
  2. Invest in an algae scrubber to physically remove algae.
  3. Use an algae remover to chemically treat excessive algae.
  4. Set up a proper lighting schedule to avoid encouraging excessive algae growth.
  5. Introduce algae-eating fish or invertebrates to keep algae growth in check.
