Nano-Tech Anaerobic-Block 2pc sump and other filter feeders

and other filter feeders

3D large rotation angle to adjust the exit water direction

For this reason you have to divide the color chart values by 10

thus no contamination of aquarium

The bacteria used in competing products are inherently unstable

Nano-Tech Anaerobic-Block 2pc sump and other filter feedersNano Tech Anaerobic Block Efficiently removes nitrate from your aquarium Proprietary technology specifically designed to stimulate growth of anaerobic bacteria. Anaerobic bacteria completes the nitrification cycle which breaks down nitrate into nitrogen gas, exporting nutrient From the aquarium. Completes the nitrogen cycle through denitrification, by culturing anaerobic heterotrophic bacteria (including species of the genera Paracoccus denitrificans
