This product review is basically pomp and circumstance. The item is an essential part of the biOrb fish aquarium setup and really those who have such an aquarium know they need it. If you are deciding whether or not to purchase a biOrb aquarium please read. The air stone is essential to dispersing the oxygen into the tank at a better rate than other aquariums. If you choose a biOrb and don't take care of it your air stone will dirty much faster and need replacing at a higher frequency. If handled to roughly it is possible to break. The stone seems pretty durable but keep in mind that like all important parts of a fish aquarium it is not to be neglected. This is a great item and there are compatible versions out there but in my experience are not as durable and efficient as the Reef One Air Stone. Great item, and lives up to its description.

I read a lot of the reviews before purchasing this airstone. I did read that any ordinary air stone would have worked but i wanted to make sure that it would fit. Putting this on was a breeze and mine did not crack. I never forced it on it just slid on. I bought my tank used so when i found out I was missing this after a few months of hearing the air bubbles I decided to change the filter. This has no silenced my bubbles and I will sleep easier at night! I would recommend to anyone with a biorb tank! I have also included a few photos to help fellow buyers!
