The ISTA CO2 Diffuser Glass External is a handmade, elegant diffuser that will connect to the outlet of an external canister filter to allow effective dissolving of CO2 into the water column.
Simply connects to the canister filter outlet tubing, replacing the original filter outlet.
This diffuser suits a 16mm internal diameter hose.
The diffuser has a large internal diffusing space, and uses the water flow to increase the CO2 dissolving rate.
This item has a built in diffuser and outlet pipe for your filter and can be used on tank glass thickness between 5mm and 12mm.
ISTA CO2 Diffuser Glass External – How to use:
Connect canister filter outlet to the large glass pipe.
Connect CO2 pipe to the small glass pipe.
Use suction cups to stabilise the glass diffuser on the tank.
