How to Get Rid of Algae in an Aquarium
8GARDEN AQUARIUM GUIDE
Algae taking over?
Find the cause, clear what you can see, then choose the right support for your tank.
1. Shorten excess light → 2. Remove visible algae → 3. Clean and change some water → 4. Test and adjust feeding → 5. Consider a suitable treatment
What does your algae look like?
Green water
Water itself looks cloudy green. Reduce long light exposure, check feeding and waste, and make gradual water changes.
Green film on glass
Wipe or scrape the glass, then siphon out loose algae. Keep the tank away from direct sun.
Hair or brown coating
Lift out strands with tweezers; gently clean affected decor. Brown dust can have several causes, so observe before treating.

Read the product label for freshwater or saltwater use and for fish, shrimp, snails and live plants. Measure actual water volume, follow the dose exactly, maintain aeration and filtration, and remove decaying algae. Never combine treatments unless both labels allow it.
