Review: Fresh start tanks - I bought this substrate for a small plant tank and I love it. I wouldn’t recommend to add this to a tank that is set up and already has water in it, because it clouds bad and it did take about 24-36 hours to fully clear up, but it looks BEAUTIFUL. The substrate almost sparkles in the light, and I love the black color of it. I’ve only had plants in it for a few days, so I can’t really speak on how good the substrate truly is, but so far I’m loving it. It does come wet and you do not need to rinse it at all. Once you get past the cloudiness, it looks SO good!! Plus it should be great for plants! Review: Bought twice. - This substrate is great! It does a good job helping to start your cycle in a new tank. The sand is relatively easy to clean with a siphon as long as you're careful. Make sure the sand does not go down your drains. The color looks great. I had to deep clean my tank (included trashing all my substrate) because my fish died of disease and I ended up buying this again because I liked it so much. One bag is a good amount for my 5.5 gallon. ## Features - Seeded with bio-active live nitrifying bacteria - Cycles aquarium instantly - Contains bio activated live nitrifying bacteria - Great for aquatic plants ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.6 out of 5 stars 1,544 Reviews | ## Images ![Bio-Substrate, Galaxy Sand, 5lb (Wet) - Image 1](https://m.media-amazon.com/images/I/71ooYoqDL6S.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Fresh start tanks *by C***E on August 1, 2026* I bought this substrate for a small plant tank and I love it.
