Fish Tank Experiments - BioHome BioGravel (Going for Zero Nitrate) Video 1 

This video is showing the history and beginning phases of an experiment in fish tank filtration to be able to denitrify the tank water through bio media use. I am using BioHome BioGravel media.
While I am not sponsored by BioHome or Great Wave Engineering, they did supply the materials for free for me to test on the condition that I report my findings in video.
I'll gladly link to their website here for you to look at their products. I do not make any form of commission on sales of their products.
