• You can get rid of algae from a fish tank in 6 easy steps
1. Lower nutrient levels in the water. Change the water and siphon out
the slime.
2. Lower the light levels. Sunlight makes plants grow so it will make
algae grow.
3. Keep direct sunlight away from the fishtank.
4. Use grazing snails to eat most of the algae
5. Use a razor blade to scrape glass tanks
6. Get algae eating fish such as cat fish and siemese fighters .
• To avoid getting new algae in your tank, soak plants in 1 part bleach
into 20 parts water. Dip the plant for about 2 minutes and rinse it
immediately in cool running water
