A good filtration system helps:
Keep aquarium water clean and clear
Remove fish waste and excess food
Reduce harmful ammonia and nitrite levels
Improve oxygen circulation
Support beneficial bacteria for biological filtration
Promote healthier fish and aquatic plants
Minimize algae growth caused by poor water quality
