These filter packs are designed for freshwater aquariums and are compatible with specific Tetra filter models. Always check product specifications for suitability.
It is generally recommended to replace the filter pack every 4-6 weeks, depending on the aquarium's bioload and maintenance schedule. Monitor water flow as an indicator.
While you can rinse the cartridge briefly under dechlorinated water to extend its life slightly between replacements, it is best to replace it regularly to maintain optimal mechanical and biological filtration.
The white side acts as a coarse pre-filter, capturing larger debris. The green side is a fine filter, designed to trap smaller suspended particles for clearer water.
Replacing the filter pack removes some beneficial bacteria. To minimize disruption, avoid over-cleaning the new cartridge and consider adding a bacterial supplement after replacement if your aquarium is sensitive.
These specific filter packs focus on mechanical and biological filtration. They do not typically contain activated carbon unless explicitly stated in the product description.
The filter cartridge may be clogged. Replace the filter pack with a new one. Ensure the cartridge is correctly seated in the filter housing.
Ensure the correct side of the filter fleece is facing the water intake. Check if the filter is appropriately sized for your aquarium volume. Replace the cartridge if it is due for a change.
Verify the filter is properly plugged in and receiving power. Check for any obstructions in the filter intake or impeller if accessible.
Compatibility: These filter packs are specifically designed to be compatible with Tetra EasyCrystal Filter 250 and Tetra EasyCrystal FilterBox 300 aquarium filters. Always confirm your filter model before purchasing.
Setup:
Care: Filter cartridges should be replaced regularly to maintain optimal filtration. For best results, replace the filter pack every 4-6 weeks, or sooner if water flow is significantly reduced. When replacing, do not clean the old cartridge with tap water, as this can kill beneficial bacteria colonies. It is recommended to replace the entire cartridge to maintain both mechanical and biological filtration efficiency.
