10 Pack of Compatible Air Stones for Biorb Biube Aquariums and Fish Tanks

great value

Work just fine. MUCH better than the cost of BiOrb...

Work as advertised

These work just as well as the name brand, but they don't seem to last quite as long. Quite frankly, for the price difference, it's a non-issue for me. I'll continue to buy these as long as I have a BiOrb.

Excellent deal and a great price.

works GREAT!

Received

Did not notice any scum on them when I changed them. Dont think they worked at all. The ones from BiOrb showed black scum from filtering. Get the BiOrb ones not a knock off one.

Came just as described and works well in my biorb tank!

Came fairly quickly and good value

J’ai une biorb et je n’arrivais plus a trouver de pierre a air qui correspondait avec mon aquarium. J’en trouvais seulement qui etait vrm bruyante et qui laissait echaper des bulles tres bruyante (comme si la pierre etait brisé) mais avec celle ci je n’entend plus de bruits et les bulles sont parfaite

Direct replacement for the original biorb air stone. Personally there is no difference from the original to the replacement variant. Fits the same lasts the same amount of time and has the same quality. I always use this kind now.

they do the job fine
