Filter Media for Freshwater Aquariums

Xport Bio Blocks for Freshwater Aquariums were designed to withstand pH ranges below 7. These cubes can also be used in aquariums with a pH above 7. Xport Bio Blocks have the largest surface area out of any media for housing beneficial bacteria. We have been testing this product in our 480 gallon shrimp tank since November of 2018 with amazing results.

Usage: 

• 1.5 inch Block per 20-40 gallons
• 2.0 inch Black per 30-50 gallons
• For best results, add live bacteria and a block to a cup of aquarium water 24 hours before adding the block to the desired aquarium (this will seed the filter media)

Key Features:

• Designed for Freshwater Aquariums and suitable for pH ranges below 7
• Highest porosity and largest usable surface area of any media on the market
• Creates a great feeding area for baby shrimp and fish if used in the aquarium
