Cool Product. A bit tricky to install at first. Needs an air tube and a power cable to be run to the device. Have to run both under the gravel if you want it to look really nice. Comes with some of the nicest suction clamps I've seen for holding the power/airline to the glass. The colors rotate in a pleasing manner and isn't too bright at night. Device provides a good amount of bubbles, but I wouldn't rely on this along for a large tank. Because bubble maker is on device itself, the amount of bubbles produces is not affected by depth as with a traditional airpump.

I love this crystal. I ordered what I thought was the "blue" one, but it turned out to be the multi version. So very cool. The bubbles it produces are tiny like carbonation, it's easy to control the bubble volume and it just looks awesome overall. I think I'm going to have to get the volcano and switch them out periodically. I have it in a 46 gallon tank, so it doesn't monopolize a ton of space and I have the pump connection hidden behind my plants.

Overall, it works and does what it says. The light looks cool, I think that part is the best but I'm having trouble blending it with my other decor. The bubble maker is touchy... you have to be careful it doesn't get sand in it or it will not work and make a crackling noise. The assembly of the bubble maker was also tricky but once figured out, using the knob to adjust bubbles was fairly easy to use. Expect small bubbles - not big ones. Even though the bubbles can be adjusted, it is hard to get just small bubbles to come out instead of full blast. At first my fish didn't seem to like it. The crystal decor also didn't flow with the rest of my more natural decor either so I don't use it and place the bubble maker inside a cave of rocks. Overall, get this one to intrigue kids - and consider the rest of your tank decor because you purchase.
