Boyu Ball Air Stone 6 Pack

had to con, tact the company to find out exactly how big they were and a very knowledgable young lady informed me so i went ahead and ordered them. they were delivered in two days and were very securely wrapped to prevent damage in our wonderful postal system. pleasantly surprised at what a good job these do. for the price i expected slightly lower standard air stone to the ones i normally purchase from the aquarium shop but these were easily as good. and who can complain about the price!. i will never buy these from a aquarium shop again. had one in the water now for a few monthes and no problems. well pleased.

These arrived promptly, and are perfect for my high volume of air to be blown into them.There is a substantial plastic nozzle to allow my big air pipe to be fitted, after I cut off the small end tube, with a hoze clip.I also hot welded the pipe & hoze clip to the large nozzle, just to make sure the joint was smooth (to stop blanket weed grabbing hold of it) and secure.My Pond Fish are enjoying the oxygen introduced to the warm water, and are a lot healthier for it too!I have now put the Air Pump onto a clock to only switch on during the night.I will buy these again Air Stones again, if required, and would strongly recommend them to anyone who needs to add large volumes of air to their Pond! The Price is very competitive too.

Brought these for my solar air pump for fish pond bigger then my ones I got with the pump but they work better

Worked fine and gave a nice fine bubble flow. leaks around the base a bit but not a problem.

Purchased on behalf of elderly neighbour - she was very pleased with the product

Purchased many many air balls over the years and these were rubbish. Out of 6.,4 of them had defects and the tops crumbled in my hands and the other 2 just produced 1 small stream of bubbles at the top of the air stone. I highly suggest you avoid them.

A good item for use in our pond.

Its difficult to write a review for an air ball... All I can really say that it works perfectly and its the cheapest I could find, delivery was excellent as it arrived next day... I think the fish loved it too, well at least I've not heard them complaining

Works well very good

Not the best air stones didn't last long at all

Arrived quickly--top quality--

I use these in the winter instead of the water purifiyer. It keeps the pond airated and the fish healthy. a good product and a good company to deal with.

Does the job perfectly and distributes fine air buddles over the surface. Well worth the price!

Great air stones ,good size and theres 6 of them ,very happy with this item

A bit smaller than my old ones but work OK Gran
