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.

Like the versatility of adjusting the size. Great for my hang on breeder boxes.Very good quality and easy to use.

This is perfect for my small Planted aquarium. I love it!!!

Really nice bubbles, the green color is nice. Definitely really like the easy of use and how it can be torn apart to clean. Definitely will buy more when i need to.

Weight is nice, but bubbles too big for my liking and it kind of sticks out more so than the Ziss air stones. Prefer Ziss air stones

Aquarium Co-Op Weighted Air Stone

I don't often use air stones as I have easy flow sponge filters but I did have one going in a tank and that hissing was driving me nuts. And with the stone not wanting to stay where I wanted it, it was frustrating. The weighted air stone stayed in the bottom where I put it and is much quieter! It was just what I needed

Pro: The weight is the best in a small cylindrical air stone.
Con: The bubbles produced are large. I was hoping for smaller "micro" bubbles.

Throughout the years I've tried plenty of air stones. I've roasted through the Amazon store a few times. This product takes up a little space but produce large bubbles. Been using for over a month so far. I'm ready to order more.

I did play with it and took it a part. Easy to remove. But I enjoy it as it is.

5 stars for quality and durability. The airstones are actually made out of what I believe is plastic. So there are no issues with crumbling or breaking like regular stones. I’ve dropped them and haven’t had any issues. These will probably last years. They unscrew at certain points so it’s easy to clean. I would give the stones 4 stars for bubble size because they are larger than I prefer. I don’t use airstones every day (I have multiple sponge filters), just when I’m doing water changes, adding chemicals, or need extra flow. For me personally, the bubbles would probably be too big for daily use, but I’ve never tried using an air control valve with them either, so that would be something to try out if you’re using them everyday.
