We have flow between AT4 and the supply tanks to the bioball filters.
The flow rate is much higher that of the flow from the bioball filters
to AT1 which means that AT4 would run dry before the flow would trickle
back down. We plan to remedy this by adding a float switch to AT4
which would stop flow when the water level was too low. Will update as
we accomplish more.
