Perform water changes: The single most important way to avoid algae is to perform regular water changes. Change 10 to 15 percent of your aquarium water every week to lower nutrients in the water. This will remove the nitrate that accumulates in aquariums, which is one of the main fertilizers for plants.
How do I get rid of algae in my fish tank naturally?
Change the water regularly to keep nutrients low and if you have plants, use a liquid fertiliser to actually strengthen the plants and help them to fight off algae naturally. If the tank contains no live plants then you can use nitrate and phosphate resins to soak up those spare nutrients and starve the algae.
How long does algae take to grow in a fish tank?
Once the ammonia and nitrites fall to 0 and nitrates remain stable below the 20-ppm mark, you can consider the cycling process complete. That’s when algae will begin to develop in the tank, approximately 15-30 days after the cycle’s start.
Do LED aquarium lights cause algae?
Without aquatic plants, low light conditions will favor the growth of algae, since there is no competition for the light or other nutrients. In freshwater planted aquariums, the use of a LED lighting system for aquatic plants will promote the healthy growth of plants, which will restrict the growth of algae.

What promotes algae growth in water?
Algae can multiply quickly in waterways with an overabundance of nitrogen and phosphorus, particularly when the water is warm and the weather is calm. This proliferation causes blooms of algae that turn the water noticeably green, although other colors can occur.
Can algae grow from nothing?
Algae is a lot like art in that sense too. To grow and prosper algae need water – they’re aquatic organisms. No water, no algae. They need sunlight – algal cells contain chlorophyll which enables ’em to photosynthesize, i.e., using sunlight to convert carbon dioxide into cellular material.
