Instructions - Building Towers.
- First, cut a 4” drain tube to size
- Mark and drill ¼” keyholes at every 6” of vertical distance
- Spread verticals by 3”
- Mark a horizontal line ¾” in each direction, and cut line with jigsaw
- Heat hole with a heat gun until edges start to curl
- Ream it out with a LA Reamer - a coke bottle
- Cut filter medium
Actual Process:
- Slits were made with a cutoff saw

Instructions - Operation
- Make tower
- Grow fish
- Prior to fish, use compost leachate and compost tea
- Feed tube is a ½” greenhouse water tube
- Drain the Tubes into a trough that can filter addition waste, such as an azolla trough
Questions
- Can we start g-towers prior to establishing fish culture? Can we use leachate from finished compost beds or from worm towers?
