boxtech Aquarium Air Stone, Fish Tank Bubble Diffuser High Dissolved Oxygen Airstones for Air Pump Accessoriess with 1 Check Valve, 2 Suction Cup for Aquarium Pond Hydroponic

These work great! I like how they stick to the glass.

The media could not be loaded. It’s very nice, super easy to set up and powerful. I loooove the aesthetic of it and my fish seem to enjoy the bubbles. It did brown out pretty fast on the top but I think that may just be my tank because it’s been having some algae problems.Beyond that though, it’s a good size, pumps out mega bubbles with a very little pump, is not super noisy and is just a good a great addition to the tank

Used in all 4 of my tanks for extra oxygen and my bettas love it! I got an air pump (separately of course as it states) that allows me to change the level of bubbles and what not! 100% worth the money!

This little air stone sacred out so quiet! I was like, whoa! I gotta have more of these! It was perfect for the aquariums in the bedrooms. The size is somewhat bulky and takes up more room than I'd like in the tank but it was so quiet! My 1st turn off for ordering more was the price! NOT worth more $5 in my opinion... so I thought I'd wait for a sale. In the meantime this little contraption started to change. As the stone gets acclimated to the water it gets louder and louder. The algae seemed grow faster on that stone than on my others. I've tried cleaning it but that's difficult given the shape of the product and how it's made. I got this product hoping it would be quieter than other stones, as advertised, but that feature only lasted about a month or less. Overall. I'm somewhat disappointed but it still oxygenated the water for me so it's not s complete bust!

It is super quiet, has truly fine bubbles, didn’t disturb fish or shrimps. At first I was worried, it did produce only two very weak streams of bubbles but in about 30 minutes it reached its full surface bubble production 😁I love it and would definitely order this air stoneagain!!!Paired it with hygger ultra-silent mini air pump HG-971.Update: just added a new picture it the air stone. It looks nasty and impossible to clean but it is still works great.Update 3/26/23 the air stoneworks only 1/4 of its surface, leeks large bubbles from its base. Had to connect a different air store just in case if the base will get disconnected while i am not home. Very disappointed, I really loved the tiny bubbles.Update 8/18/23 took it apart, bleached and glued with a flourish glue 2 months ago. Looks and works great.

When you have an aquarium you know that water aeration is necessary. This boxtech air stone provides the aeration my fish need completely silently and efficiently. It hasn't moved a millimeter from the spot I put it in back when I bought it; the suction cup is holding perfectly. It's a very economical and essential addition to my aquarium setup. Completely happy with it.

Very fragile and thin plastic. Did not like it. The first one was delivered crushed and broken in the box . Replacement arrived and it looked very flimsy. All it takes is two fingers to pinch it and it will break. Would not recommend.

Works well - using it for CO2. Almost like a secondary bubble counter.
