- Reduced Maintenance
- Adjustable Bubble Size
- Weighted to Sink
These are one the best air stones out there that money can buy. They are weighted to sink naturally and can be taken apart if they ever were to clog - so they can be cleaned or the disks replaced. They also work great inside sponge filters. Instead of replacing a cheap ceramic air stone every 4-6 months as they get worse and worse for bubbles, install one of these once and nearly never worry about it again. Tighten or loosen the disks to change how big the bubbles are.
Works as advertised. Just get it.
I am using the air stone with a sponge filter. Works great.
I love this air stone. Works great with co-op sponge filter. Can’t beat the quality and price. Unbelievable fast shipping.
I bought two adjustable air stones for my spunge filters I got from aquarium co-op these air stones work great in my filters .aquarium
co-op have a video on how to set them up
I don’t know who’s responsible for coming up with these little plastic air stones but they’re remarkably clever. Adjustable and easy to maintain. Most of all they’re priced right. Good job!
