Matt is trying out a built in filter in his small tank using BioGravel. He plans to thoroughly document this build and record how well it works. Here we see him getting started.

I had started ghost feeding the tank a couple weeks ago to get ammonia starting to slowly build. Last week I was out of town in Memphis for the whole week and on my return I got your package, videoed an unboxing, sewed the bag, rinsed, and got the tank started up. Last night the parameters were:

79.1 degrees F
PH: 7.0
Ammonia: 0.50
Nitrite: 0
Nitrate: 5.0

I will be charting the values every day through the cycle. Once the tank is stable and processing all ammonia to a good level, I will move the inhabitants in to the tank.
