I love the air stones they work great. But they look horrible cause of the colors. Wish you could just get them in black instead of clown puke colors. But they do work awesome.
Wasn't what I was expecting, but the design makes sense for "never clog". Not loving them for just an air stone, since the bubbles are large and can get noisy, but I am betting they will work great in sponge filters, which is next on my bucket list of fish stuff. Packing, shipping and service was great. Will be ordering more stuff in the future.
service from aquarium co-op was great. Not sure about the stones,prefer larger quantity of smaller bubbles.
The bubbles are bigger than a traditional airstone no matter how I adjust it but that's fine. It seems to work really well in my sponge filters. I have one in both of my tanks in my front room and will be buying two more for my other tanks. Definitely worth buying to save your air pump from burning out due to an old and clogged airstone.
