    I choose this sand for a bio- orb project, i love the smoothness of the granules and the color. A very nice top coat.

    Updated Review (April 2023):
    I was excited to use this substrate again, as I have it in four tanks where it’s the perfect solution. But my latest purchases (March/April) had color inconsistencies, and the substrate smelled strongly of wet paint. This was true for bags purchased from Amazon and from a local pet retailer. I asked two other people what they smelled without telling them what I smelled, and they immediately said, “Paint.” I contacted the manufacturer and was told to return the product to the places of purchase. Will be switching back to Seachem. Would rather spend hours rinsing flourite sand than risk a substrate that smells unsafe.

    Original Review (October 2022):
    I bought two bags to do two Fluval Spec III tanks. I rinsed the first one, and there was zero dust. Seems like any dust had stuck to the inside of the bag when I poured the contents into my rinse bucket. So with the second bag, I poured it straight into the dry tank. There was again zero dust when I filled the tank (using a plastic lid to diffuse the water so I didn’t stir things up). I haven’t tried this substrate with plants yet, but I’m planning to grow low maintenance species of cryptocoryne, anubias, and buce that have no trouble in my other tanks that have cichlid sand substrate. I don’t anticipate any issues. That said, I am prepared to supplement with root tabs if needed.

    Beautiful substrate that’s easy to clean
    Looks great in my rimless tank on a black base.
    Plants look outstanding against it and it’s very clean out of the bag, just a quick rinse and your done.

    My daughter loves fish-she purchased a betta fish and the accessories needed for him to thrive with her own money-unfortunately over time poor Wavy died. A few weeks later Curvy was purchased. Eventually this betta fish seemed to struggle-so after we determined it wasn’t his water quality that was poor-I figured it was his environment that needed some enriching. I went all out-buying new plants, some different food and this new gravel because I thought this would be better for him to lay on because it was more smooth than the larger gravel rocks we had. We did a tank change and put Curvs back in his newly remodeled home-but he wasn’t as excited as I thought he’d be. He didn’t thrive he seemed scared of the new plants-and wasn’t a fan of the different shaped food bits-but he did seem to appreciate the smooth softness of this gravel. I probably should have changed out one element at a time. He did eventually pass-and we have concluded that fish are just not our thing. I liked this gravel-but I cannot bring another fish in our home because I feel badly that I won’t be able to do enough to keep it happy.

    I recently decided to upgrade my betta fish tank setup, and after some research, I came across the Betta Fish Sand Substrate. Let me tell you, this product exceeded all my expectations, and my betta fish are loving it!

    First and foremost, the sand substrate is of exceptional quality. It is finely granulated, providing a smooth and comfortable surface for my betta fish to explore and rest on. Unlike gravel or rougher substrates, this sand is gentle on their delicate fins, ensuring a stress-free environment.

    The natural appearance of the sand is another highlight. It beautifully replicates the soft, sandy bottoms found in betta fish natural habitats, creating a visually appealing and authentic aquatic setting. The sand’s neutral color also enhances the vibrant colors of my betta fish, making them truly stand out in the tank.

    One of the greatest advantages of this substrate is its easy maintenance. The sand is easily sifted and cleaned, preventing debris from accumulating and keeping the tank water pristine. It doesn’t cloud the water like some other substrates, ensuring a clear and healthy environment for my fish.

    Additionally, the sand substrate promotes the growth of beneficial bacteria, which aids in maintaining a stable and balanced aquarium ecosystem. This has had a positive impact on the overall water quality, contributing to the health and vitality of my betta fish.

    In conclusion, I cannot recommend the Betta Fish Sand Substrate highly enough. It offers a perfect combination of aesthetics, functionality, and ease of maintenance. My betta fish are thriving in their new environment, and I couldn’t be happier. If you’re looking to create a beautiful and healthy habitat for your bettas, this substrate is an absolute must-have!

    I would definitely give it a solid 5-star rating and will be using this substrate for all my future betta fish setups
