The aqua gravel looks great in my 50-liter tank. My fish seem to enjoy the surface, and the water stays clear. It’s easy to add and doesn’t stain the water. Perfect for a beginner setup.

I used it in my community tank with guppies and shrimp. The gravel holds up well and doesn’t break down quickly. The colour is vibrant but not too intense. Slightly more expensive than regular gravel, but worth it for the look.

Great quality and consistent size. No discoloration after two months. My planted tank looks more natural now. Easy to maintain and clean.
