Fittings
Theres no need to get elaborate and expensive with fittings. Most fittings shown were scrounged. PVC offcuts, a couple of lids from 20L plastic drums were used for making the auto syphon (or 'bell syphon' as it is sometimes called). I used 1/4 inch and 1/2 inch black poly garden irrigation pipe for the fill system. The main expence items are the submersable pond pump (might cost 30 - $70, the timer 10 - $15) the rest can be improvised from reused materials. I chose to buy the plastic tubs as they are fairly cheap.
