Aquaponics (Growing Plants with Fish Poo)

Step 3 Install drain on the grow tub

This is the bit that took the most research - how do I make a system that is simple and reliable?
Having worked in a factory before, I know that level sensors and valves and timers can find all of these great and interesting ways to fail and make huge messes.

The solution to this is the Bell Siphon. It is incredibly simple, and incredibly reliable. Perfect!

For this system, the bell siphon consists of:
- The standpipe attached to the drain hole on the Grow Tub.
- The 2" pipe and cap acting as a "bell"

First, the toilet bowl assembly needs to be cut apart so that we are left with a 4" pipe on the end of the Bulkhead Fitting (a bulkhead fitting is a fitting that is designed to attach a pipe to a hole in a tank)

Next, a hole has to be drilled in the bottom of the Grow Tub, large enough for the Bulkhead Fitting, but not too big. Assemble the Bulkhead Fitting in the hole as shown.

in my aquaponic aquarium filter, i cut holes in the sides of the toat the plants grow in, and have that toat sitting inside a slightly larger one, with a hole in the bottom. it drains directly out the hole in the bottom back into the aquarium, through a hole i cut in the lid. it saved on buying parts and there are fewer moving parts that could fail and flood my appartment
