The crystals add a beautiful, natural glow to my 2-gallon betta tank. They look like real underwater elements and make the tank more inviting. Easy to install and stay in place without floating away.
Karen Roberts –
I love the light blue crystals—they match my tank’s decor perfectly. They don’t cloud the water and stay stable even after a few weeks of use.
Karen Coleman –
Great value for the look. The dark blue ones give a more dramatic effect. My fish seem to enjoy the environment, and the tank looks much more vibrant now.
