Air Stone (3.5 x 1cm), Aquarium Aeration Stone, Uniform Bubble Flow

My orb had no bubbles at all. While looking for reasons as to why it might be and knowing it wasn’t the pump at fault, I read that someone replaced the air stone. Took out the old one, put the new one and I have never seen bubbles like it. It’s the first time time I have done this and I have had my tank for years so it probably needs replacing more frequently. Simple little thing that has already made a huge difference. Cheap at the price and came next day as per prime. Definitely recommend. Cheaper than a pump.

Good biorb

Brilliant item, good service, good value 👍

Item is as described, arrived promptly.

This is the second time i've bought these from Amazon as it is so difficult to find them in pet shops.They are competively priced although for one little airstone they're not cheap. I agree that in the description it says two airstones in the pack,that should be altered.These used to be a two pack for not much more than todays' price,but this pack isn't available now. I have had no problem with Bio Orb airstones ever.They are a snug fit so i am always very carefull not to push down too hard when replacing them.The water quality is good so i assume they are working well.5* because they've always done what they are designed for and i've had no problems.

Really good does the job fine. Good price.

Good customer service will definitely use this seller again. Thank you

Easy to change and makes a real difference to keeping the tank clean

Non ho fatto nessuna fatica ad installarlo le istruzioni nella confezione sono chiarissime. Una volta installato ho subito notato la differenza nella potenza dell'areatore.

This is a must have item. Fits very snug as it should. Why I prefer OEM parts/accessories, etc. This stops the large high pressure air bubbles 🫧 also it disperses the oxygen properly. I am new to this Biorb Fish Tank 🐟 I haven't had pet fish since I was a young child I don't remember much as I was to young to care for Tank, filter, fish, etc. I definitely notice my Fish are feeling better by breathing better since I installed this. FYI make sure you have a new replacement Biorb filter since you shut filter, air off pull tube to install this. Seriously, this really makes a difference. Get one and replace when needed. We'll worth it. Next time I will order extras so I have them. Makes no sense to replace filter and not this for $6.99.

Prima luchtsteentje, nog wel aan de prijzige kant, maar altijd beter dan de vorige prijs. En ook veel beter dan het namaak product.

Repuesto original y de buena calidad.
