  • Weighted to sink
  • Modular height
  • Easy to clean

Keep your aquarium well-oxygenated by using an air stone with your air pump. An air stone is used to diffuse the air into smaller bubbles that agitate the water surface and increase oxygen levels. We built our weighted air stones with little, modular discs that can be snapped together or removed to create the perfect size. Plus, its small diameter is perfect for fitting inside common air-driven devices, like sponge filters.

Impressed

I got 4 of these airstones to give them a try and I am very impressed with them. I have been using them for a month and they have not degraded if flow whatsoever. I was worried about the bubbles being too large/loud however that is not the case. They have the same bubble size as the oase airstones I had laying around however those degrade fairly quick and clog. I suspect these will never clog and if they do a quick sink rinse will fix it as they are just solid plastic.

Works Perfectly and Stays Put!

I absolutely love these air stones! They stay perfectly in place and put out a smooth stream of bubbles. Way better than any other air stone I’ve used. No floating, no fuss. They’ve definitely earned a permanent spot in my setup.

Weighted air stone

Not heavy enough and insufficient airflow for my liking

They Get the Job Done

This pair of airstones tells it like it is. They're nice and simple, high quality, with a refined no-frills design. They're not going to be the perfect accent to your painstakingly aqua scaped pro $1500 setup, but they will plug and play into your everyday normie tank. They are a good color to blend into the background and produce nice consistent bubbles. I stuck it at the bottom of some extra filter hose along with a sponge and now I've got a cheap little air stone filter for my anubias/invert 8gal.

Great airstone

The airstone is great this is my first time buying this and I honestly think it was worth it. It took a bit of time for it to sink so you have to be patient. I adjusted it until I could barely hear the bubbles in my 10g.

Best airstone

Love this airstone! Drops right down to the bottom even with a ton of air going through it. Highly recommend!

Works as advertised

Stays where you put it . Bubbles are fairly adjustable. I like how it is easily hidden behind plants and gets rid of stagnant corners in my aquarium.

Too loud for undergravel

Got these because I liked the design and non-clogging aspect. Unfortunately the bubbles they produced were too big. Putting them in the lift tubes of my undergravel filter was just way too noisy. If you have an undergravel with big lift tubes, I would recommend the Ziss air stones instead.
