Bio Filter Design & Fabrication Apprenticeship

I began construction on more ponds on the porch which feed into the central biofilter. They will mostly be for plants, as they will be a welcome addition to the cycle, taking up the free nitrogen and giving us freeway adjacent dwellers some much needed extra oxygen.

Also spent a few hours at the local Koi Nursery fabricating biofilters as part of my apprenticeship there. Can’t wait to go back next weekend.
