Fish tank atomizer, CO2 diffuser, with suction cups and U-tube, for all types of aquariums

Works brilliant.

Great bit of kit for very little money. 100% recommend for the price. Very sturdy and well built. Was expecting to have to soak in water for 24 hours for micro-bubbles, but instantly working at 4bps co2.

Tried over a period of weeks thinking there was something wrong with my set up. However after testing with a different one which worked fine I can confirm this model just doesn’t work

This is the first time that I have used one if these . It works perfectly to produce very fine bubbles after two or thee days of being underwater. Initially the bubbles were large but as the ceramic disk absorbed more water they became very fine.I have ordered some extra disks for it.I use sugar ,yeast and yeast nutrient to produce Co2 in a 2 ltr plastic pop bottle. Its a relible cheap way to do so.

Works great very happy with it

The steel corroded within 6 weeks but worked fantastic up until then

The media could not be loaded. From diffuser, you will expect nano bubbles. Those are massive on the beggining, but after a while settle properly. Good value for money.

Not a lot of CO2 is diffused through the plate. I've tried increasing the presure to very high but the tubes litterally pop off the fittings before getting to the levels I'd expect.Note: It's been in my tank for months now. It's not a problem with the ceramic plate not being fully soaked yet.
