Setting up Recirculating Aquaculture System for Concrete Tanks 

As part of the expansion of the fish operations, the next phase is to improve the amount of control over the conditions within the ponds. Currently the water is only changed once in 3-4 days depending on the weather conditions.

The plan is:

  1. Setup RAS circulation with solid settlement and bio-filters (Ultra-violet light based)
  2. Setup a solar system to power the pumps moving the water
  3. Add a covering over the tanks to produce a “green-house” like effect to maintain the water temperatures in ranges that are ideal for tilapia
