Plastic totes are readily available. You just need to decide on the size you will need for your system. Mine has enough room for 8 three inch pots. Drill holes the proper size for the pots you are using and evenly spaced apart. Center a 3 way hose barb on each pot and connect them together on the sides of tote using flex tubing. Using a 90 degree hose barb with pipe thread on one end, connect each end to a 3 way pvc connector as shown in photo. On the bottom of one of the pvc connectors is a hose barb to connect to pond pump. The other side has a valve for draining the water. Exactly which pieces you will need depends on the particular configuration you are using. Place air stones and pump at bottom. Connect 1/4″ tubing to air stones and run tube out of tote to air pump. Connect 1/2″ tubing from pump to hose barb at top of lid. Attach Thermocouple and pH electrode to the side and inside of tote so they sit in the water.
