Rated 3 out of 5 by Misscatbrat Pretty but not stable
This is very pretty to look at and watch the colors change and it gives a good amount of bubbles but the suction cups do not work very well. Every time I get them securely fastened to the bottom of the tank at least 2 will pop up (even if the air stone is covered with gravel) within a day or so, thus leaving the stone partially hanging in the air. I've tried it on a clean tank bottom as well as an established tank bottom and it does the same thing, every time, to both. Very frustrating - to the point where I'm about to take it out of the tank and say the heck with it.
