Skyzone Air Stones for Aquariums,4cm Bubble Release Airstone Fish Tank Oxygen Stone Disc Bubble Diffuser Bubble Release Tool for Air Pumps Fish Tanks Buckets Small Ponds(Pack of 4)

These work great. Lots of bubbles. I have a good pump though.

Nothing to diss like . For a pond.

The media could not be loaded. I've 3 tanks so this pack of 4 was perfect for me, just means I've one spare incase one breaks or what not.X2 190L tank and X1 64L tank (currently cycling) all have these disks and literally can't fault as of yet, just make sure you follow the directions to fully submerge and soak them before use.Video included is my cichlid tank and the bubbles are super powerful, 190L tank so would probably really only recommend for big tanks with fish on the larger side as any tetras, Bettas, anything on the smaller side will struggle to swim with the current, bloody wierd fish love playing in the bubbles, creates plenty oxygen for your fish and keeps the water flowing nicely.Previously had a bubble bar but it crapped out so opted for a disk instead and honestly it's just soooo much better!Just for anyone buying please be aware it is literally just the X4 disks you get, no tubing or pump. But as I was just replacing previous ones that wasn't an issue for me.If you wished to use for a smaller tank you can purchase little adjustable dials which just plug into the air tubing as well which adjust the flow to your liking, that's what I've used in my other corner tank as I've a few smaller fish.

It does a good job,

Simply better than the rest

AAA+ great goods easy transaction great price and speedy delivery; ...they were sealed in a bag but were a bit dusty, caused in transit maybe by being face to face in the same packet...a rinse under the tape sorted that out - working really well...recommended

The media could not be loaded. All four leaked air through the joint of the air stone instead of the even distribution throughout the stone 😒😒

Don’t waste your money , tried 4 stones not a bubble between them !
