#grownostr #aquaponics #biofilter here is another filter I added to the system. Running during the day, lava rock, pond baskets with mint, elderberry, mulberry cuttings.

Just runs continuous, once the mint takes root, should filter the water well. It is a medium concrete tray from home depot.

I have a 1/2” bulkhead with a male pvc fitting on top. That keeps the water level about 1/2” high.

The pump to pvc is 1/2 “ irrigation tubing, into a 1/2” pvc female, 3/4” T slip.
