Review on 🌊 Marineland LED Bubble Ring Crystal Decor - 4x2 Inches by Carrie Green

Despite the mediocre reviews, I decided to try this bubbler ring and crystal decor. The bubbler works fine for me, although you have to make sure it sits very securely under the substrate to keep it in place. The LEDs change between five different colors and there's an on/off switch (I leave mine on as a kind of moonlight at night). This bubbler goes well with the Magic World decor set.
