Use one 1. 5 ? XPort Bio Block for every 20 to 40 U. S. gallons ( 75 to 150 L ) or one 2. 0? Xport Bio Block for every 30 to 50 U. S. gallons ( 100 to 200 liters) of system capacity, more for heavy bio loads. Recommendation: Do not use different bacteria products in an aquarium, particularly during startup! When an aquarium is new, the available nutrients for bacteria to consume are scarce and if the kind of bacteria you introduce requires organics, they will likely not be available and the two different bacterial cultures can fight each other. It is best to start out with Micr?Bacter Start and cycle the tank, and then progress to Micr?BacterCLEAN at cycling completion. Then progress to Micr?Bacter7 or FlorinBacter7at 4 to 6 months of age. This will provide the cleanest and fastest route to meet your goals and provide a beautiful and sustainable bacterial ecosystem. Particularly do not introduce foreign strains of bacteria such as "live sand", pre-cultured dry man made "live rock, " etc. It is ok to use rocks from other aquariums that have already cycled and live rock purchased from stores. All forms of man made or natural live rock (except dry pre-cultured), aragonite and marco rock will work fine. If you introduce the wrong strains of bacteria, at the wrong time, you can slow down the whole process.
