The substrate works well in my Betta tank. The fish seem more active and the plants have grown nicely. No staining and the water stays clear. The granules are fine and don’t make the tank messy.

I’ve used this for a few months now. The pH stays stable and the plants are thriving. The texture is smooth and doesn’t scratch the fish’s fins. A good choice for Betta keepers.

Great for beginners. Easy to mix in and the fish don’t seem stressed. The roots grow well and the water quality has improved noticeably.
