Product Description

CO2 diffuser is a carbon dioxide distributor, used to increase dissolved CO2 levels in freshwater aquariums when little space is available. It is attached to the aquarium edge, up to a glass thickness of 15 mm (1/2"), with a magnetic holder and ensures a distribution of up to four CO2 bubbles per second. In the aquarium the diffuser operates as a “stand-alone” solution with a small submerged pump, which draws in the water and thoroughly mixes it with CO2. The efficient diffuser ensures that no carbon dioxide is wasted. The diffuser is suitable for freshwater aquariums up to 1,000 liters (264 US gal.).

Installed it in place of a nozzle. Works fine. The bottom spray part is not the same as in the picture. It is about 2" long. Which I like even better as it works like a spray bar and diffuses co2 enriched water to the bottom of the tank right on top of carpet. The tube is not clear and rather slate grey. After 2 weeks it became opaque due to built up inside. I do not see it as an issue so have not tried to clean it.
The pump (that I do not use) is really flimsy. The protection cover broke off immediately.
The spare Tunze magnet is nice to have but it is not the same as my ATO magnet. The magnets are completly exposed on the outsides (the sides that go against the glass). They supply small silicone dots intended to be ised as protective buffers but they look unreliable. The ATO magnets in comparison have full covers and rubber rings that protect the glass from any potential scratches.

I have purchased other Tunze products in the past and am generally very happy with what they make. This diffuser really did a great job at infusing the water column with CO2, however the pump is sub par for a TMDE product. I had a small pump that I wound up using in its place.

Overall rating is 3 stars but would be much better if they added a better pump to the system.
