| Check filter flow | Weekly | Clean impellers and tubing if flow slows |
| Inspect media condition | Monthly | Replace if worn or damaged |
Biological Filtration Benefits
Biological filtration is key for reef tank health. It helps keep water clean and safe for corals and fish.
This filtration uses natural processes to remove harmful waste from the water. It supports a balanced aquarium environment.
Nitrifying Bacteria Role
Nitrifying bacteria break down fish waste and uneaten food. They turn toxic ammonia into less harmful substances.
These bacteria convert ammonia to nitrite, then nitrite to nitrate. This process helps prevent poison in the tank water.
- Ammonia is highly toxic to fish and corals.
- Nitrite is still harmful but less than ammonia.
- Nitrate is the least harmful but should be controlled.
Live Rock And Bio Media
Live rock provides a natural home for beneficial bacteria. It helps filter water by hosting these tiny organisms.
Bio media in filters offers extra surface area for bacteria to grow. This boosts the tank’s ability to clean itself.
- Live rock adds natural bacteria and helps water flow.
- Bio media can be ceramic rings, sponges, or bio balls.
- Both increase bacteria population for better filtration.
Optimizing Biological Filtration
Keep the filter media clean but do not remove all bacteria. Rinse media gently in tank water to avoid killing bacteria.
Maintain good water flow to supply oxygen to bacteria. Avoid overfeeding fish to reduce waste and ammonia build-up.
- Rinse bio media in aquarium water only
- Ensure water flows well through the filter
- Feed fish the right amount to reduce waste
- Test water regularly for ammonia and nitrite
