The little guys (Tilapia fry) are about to out grow their current housing. That is the aquarium they have been in since Chan rescued them from the system filter. But, they are still too small to defend themselves against the larger fish in the fish tank. So, they can't go into the 1,000 liter IBC tote just yet.
We cut a barrel, added an SLO (Solids Lifting Overflow) and a temporary filter made from a 20 liters (~5 gallon) bucket. This will work until I can get some glass panels to partition the aquarium into a sump / filter for the new barrel they will call home.
A few fotos of the test run after completing the build yesterday.
