Nano Glass Co2 Diffuser
Getting Basic, Easy, Simply, Nano, Cool, Low Price, Good Looking!
It is suitable for Nano tank. (Maximum up to 20 US gallons)
You could refer the diffusivity result on my YouTube video as above.
It is useable for the new design on the outlet of glass. The outlet is rougher than the general Nano glass Co2 diffuser.
It’s worth to try and using it.
