Biological Filtration
Biological filtration uses good bacteria to break down fish waste. These bacteria live on filter surfaces and tank decorations.
The bacteria change harmful ammonia into less toxic substances. This helps keep water safe for fish.
- Removes ammonia and nitrites
- Supports a healthy aquarium environment
- Works continuously without replacement
Chemical Filtration
Chemical filtration uses materials to remove dissolved wastes and odors. Activated carbon is a common chemical filter.
This filter type cleans the water of toxins and discoloration. It keeps the tank water fresh and clear.
- Removes harmful chemicals
- Eliminates bad smells
- Improves water clarity
Water Conditioning Products
Keeping aquarium water safe is key for ornamental fish health. Water conditioning products help remove harmful chemicals and balance water quality.
These products prepare tap water and create a stable environment for fish to thrive. They include dechlorinators, beneficial bacteria, and pH adjusters.
Dechlorinators And Chloramine Removers
Tap water often contains chlorine and chloramine. These chemicals harm fish and need to be neutralized before adding water to the tank. Dechlorinators make water safe by removing these substances quickly.
- Neutralize chlorine instantly
- Break down chloramine safely
- Remove harmful heavy metals
