Boyu CO -100 Aquarium Co2 Diffuser

Works perfectly well. Using it with a DIY Co2 setup. Bubble size is small enough. I do wish that the bubble size was even tinier but that would mean very high line pressure will be needed to operate it.Overall very good for a diy co2 set up.

Works fine. Handle with care, very delicate.Good for the price.

Bad quality of glass with high costAs like the design I hv purchased it. Received in good state but during installation (i pushed transparent pipe in this diffuser) its brocken down .Believe me pressure was minimal.After that Ihv purchased another diffuser (4 in1) which is so cheap but qulity is so good compare to boyoMy suggestion: search for another option (bubble counter+check walve +diffuser)

I received the product few hours ago. It is working well with my diy yeast CO2 generator. Bubbles are extremely minute, and spreading all over the aquarium. But Boyu should have at least sent one silicon vaccum pad for fixing it to the glass. Shall have to arrange/buy seperately. Hence, cost wise it didn't meet my expectations.

still working in good condition. boyu specialist in aquarium product. my all aquarium products are boyu.

The bubbles are too big like that of an air stone. It is useless as a diffuser. I am returning it

Good diffuser. Working well for co2. Would have liked a suction pad along with it. Hence the 4 stars.

I bought this to work with my yeast reactor. It works beautifully diffusing micro co2 bubbles. A very good buy. But have to wait and see how long the ceramic lasts.Edit: it doesn't work evenly anymore. The bubbles are big and doesn't diffuser properly
