I will be investing in a pH meter soon then.

I purchased a 10 gallon rubbermaid today, as well as some pvc for air dispersion.

I built a rectangle out of PVC that outlines the bottom of the container on the inside, it has a total of 6 branches running the width of the container, and the two outside pieces run the length. I feel this should evenly disperse air as I will be drilling many holes in the PVC.

I will be buying the air pump tomorrow or the day after, I will keep you updated on progress.
