Why Use Matrix in Your Tidal Filter?

Biological filtration is one of the most important parts of maintaining a healthy aquarium. Beneficial bacteria living on filter media help break down fish waste and uneaten food by processing ammonia and nitrite, supporting a safer and more stable aquarium environment.

Seachem Matrix has a highly porous structure that gives beneficial bacteria room to colonize. Using a Matrix cartridge in your Tidal 55 filter helps strengthen the biological filtration capacity of your aquarium system.

Directions for Use

1. Rinse the cartridge gently before first use.
2. Place the cartridge into the Seachem Tidal 55 filter chamber.
3. Position it where water flows evenly through the media.
4. Rinse gently as needed during maintenance using aquarium water or dechlorinated water.
5. Do not replace all biological media at the same time.

Maintenance Tips

• Rinse gently as needed to remove detritus and maintain water flow.
• Use aquarium water or dechlorinated water when rinsing biological media.
• Avoid untreated tap water because chlorine or chloramine can harm beneficial bacteria.
• Do not scrub the media aggressively.
• Pair with Seachem Foam, MatrixCarbon, Purigen, or other media for complete filtration.
