I recently saw a report about the Tohá System that uses filtration with worms and a column of stones of different particle sizes to remove solid waste from residential sewage treatment at the same time as treating the wastewater.
Does anyone have experience with treating fish waste with this Tohá system, returning the water that percolates through the pebble column to the aquaponics system?
Does anyone have any information or comments to make about the pros and cons of this system combined with aquaponics?
