Aquarium Co-Op Weighted Air Stone

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.

Great product, bought to incorporate into all of my sponge filters.

These are just as described and very handy to have. I love the green color since my aquariums are all planted!

Works great and a great value

This air stone is on my favorite list. It stays on the bottom. It’s worth the price and you’re going to love it.

Pleasing little thing that looks good in any situation. More importantly, function is top of the line. I can see replacing all my air stones with these eventually.

I use them primarily with my Ziss brine shrimp hatchery. They work perfectly for this application. If I had nano fish tanks I would use them as my first choice because they work! Highly recommend

Like the way it sink fast where you want it!

Bought some weighted air stones from Aquarium CooP. Terrific product.. will be buying more.
