Step 10: Maintain the System
At this time, we have been running the system for over 2 weeks. The 5 fish are still alive. When it rains we drain off water into the garden. The pump has needed to be wiped clean a few times. We will have to add a coarse pre-filter, like a bucket with holes.
I have to add a section of plants to filter the water.
The next step is a fish autopsy. It shows why one fish with a stuck hook died.
