Review on 🐠 Cafurty Practical Air Bubble Increaser: Enhance Oxygen in Aquarium Fish Tank with Adjustable Oxygen Increase Ball Air Pump Accessory by Lori Okuno

I may not have read it all, but it's only with the blue part in the photo, not the hose, so no bubbles. You need to buy a hose for this product and connect it to the tank properly to use it and get blisters. There were no instructions or information about the product in the box and it was packaged in a small ziplock pouch. Overall I'm not happy with this product, I think the advert is misleading but I admit it might be my fault for not reading everything when I bought it as I've just received the aquarium. One felt that the product was of good quality and not cheap, the delivery was fast.
