| Thanks for the pictures, and diagram Smithson. The venturi drain is a very nice idea. Don't want the vegies, although very nice set up. Their filtering capacity is very nice, but it needs a lot of room. Would also increase the amount of labour needed.
The venturi drain is something which I will try and incorporate in future doings as my wife's fish farm evolves. But in a tank, I would still like to have a bottom drain, for obvious reasons. tsicar brought up aeration. I would like to tap other peoples idea about this. I am planning to use a Supercharger, whose air will be distributed via a manifold, delivered with air stones throughout the system. The system is of the recirculating type, with 51 tanks each holding 1 cu M of water. |
