- 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.
Customer Reviews
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.
These work great! So much better than having to tie a weight on a regular airstone and they blend right into the plants. Highly recommend 👍👍
Maybe these exist out there but I saw em first from Cory. Was struggling in my quarantine tank to keep the stone down. What a game changer. Simple and so useful. One of those make me a million ideas that I wish I had. Good fortune to the aquarium coop team.
what can I say they do what they are designed to do, and the weight keeps them on the bottom.
The only air stones we use! Love that they are weighted and remain in the bucket when transporting fish from swaps and club events.
This new weighted airstone is ingenious. It sinks and stays put, can be tucked into foliage or behind a rock—my minnows actually enjoy riding the bubbles it generates. Wonderful product for a corner of a tank that needed more aeration.
I really wanted to wait a while before submitting a review for these.
So far I've been using these for over 3 months in sponge filters. With the ziss air stones..they would constantly get backed up and ruin air pumps if I didn't clean it at least monthly. Pretty annoying when you have 10 aquariums.
These air stones have yet to clog or ruin an air pump from back pressure. I'm on my second pack, slowly replacing every one in my fish room with these so I can be maintenance free!
So these airstones are super cool, they come apart to make different sizes and they fit in a sponge filter if needed (which is what I do). They are green and blend in with my live plants (if I use them outside my sponge filters). Honestly I go to this place for all my aquarium needs. I follow them on you tube & I live close to one of their partner retailers in Cookeville, TN. If I can’t buy it there, I hop online to get it here. Aquarium co op has my heart forever, HUGE FAN!
These stones do what they say. They do sink , are quiet, efficient and do not clog. Zero complaints. I’m running 4 of them and sure to grab a couple with each future order.
Another great product from Aquarium CoOp. The weighted air stone sinks right away and outlast any other air that I’ve tried in the past. I’ll be replacing all of my old air stones with new Aquarium CoOp air stones.
