Works great. Lots of bubbles. Best air stone I think I’ve ever had

I saw some reviews saying half the stone didn't work, but I hoped for the best and purchased this product anyways. Lo and behold, when I plugged my new air stone into my 4 watt air pump, only half the stone bubbled, but the bubbles were great bubbles. Credit where credit is due. Now looking into the matter, the instruction manual claims that if only half the air stone works, then the problem is with the air pump not being strong enough. I guess my aforementioned air pump with a power of 4 watts was simply not enough. The details of this product recommend use with an air pump of > 4 watts. > is not >= I guess, and I can't say I didn't see this happening because I was warned. So yeah, unless your air pump power is greater than 4 watts, the air stone won't bubble completely, and it's a lowkey weird look. The suction cups are great though, and really hold the stone in place.

Works well

I thought it would be too big for a 75 gallon once I saw it, but it wasn't. My fish, a tiger oscar, loves this air-stone. He spends a lot of time in it, probably because he likes the feel of it. The wave maker gives him all the air he needs, but this is more for his stimulation and fun. He actually seems like he guards it when I'm doing a water change. The suction cups make it so it can't move or make a racket against the glass, which is nice.

Has been in my tank for a couple years, AND there's hard water here, and it's been no issues. My koi chill in the bubbles, and I just let that thing hang there. It takes the bigger tubing size, and you need a one way valve so keep that in mind. I don't remember if it includes one, but I bought an air pump and they were in there, and life just changed man. It makes zero noise, tons of bubbles, and it's got great flow even for a 50 gallon tank.

I bought two of these a few months apart. The first one works great and as it should, the second one had the bottom separate from the body causing a major air leak in the system. I had to retrieve it, dry it and JB Weld the bottom back on to avoid buying another one. Addition: The JB Weld let go on the one I fixed and the other one failed as well. I had to buy 2 new ones to replace both. I guess I have to either find a replacement or resign to the fact that I have to replace them every 6-8 months. 3 months in on my next one and the bottom blew out too. These are terrible for use in large ponds.

EDIT 1/21/2021 I was sorry to find the stone failed on me after using it once a month or two on average. Maybe others know if this seems like a reasonable lifetime for an air stone, but it seems like I haven't used it all that much. Just so you know, I used it for compost tea (really organic nutrients and earthworm castings, mostly, but a half-quart of compost too). I've cleaned it mostly with jet on hose nozzle after each use. Scrubbed it with bleach solution and wire brush about 3-4 times. So failure could be my own dang fault, I don't know. Seems ok, except the bubbles are a bit larger than I'd hoped. Mainly, I wish they had fitted it with a 90-degree outlet like some similar models. I used their measurements to conclude it would fit at the bottom of a standard 5-gallon bucket (for compost tea). Unfortunately, unless I cut off one of the legs it will not sit flat without badly kinking the tubing. Next time I'll purchase a disk with a 90-degree connection, which would allow more universal applications.

The seller gave me a low-quality Chinese substitute

Llevo una semana usándolo y todo bien hasta ahora.
