    • Excellent product not affecting water clarity
Color: Bio-Stratum Size: 4.4 Pound (Pack of 1)
I was skeptical about using this as a substrate concerned about cloudiness in the water. This was so easy to use and looks great as I covered it with the gravel but still have the benefit of the mineral rich benefits and still have excellent water clarity. Excellent product that will be used in other tanks. ... show more

    • Keeps plants thriving
Color: Bio-Stratum Size: 8.8 Pound (Pack of 1)
Doing great at keeping my plants alive and thriving. Just make sure to avoid putting this soil under heavy objects such as rocks or driftwood as it can begin to compact, I'd recommend filling with sand or gravel under decorations and natural driftwood and rocks. Other than that, great aqua soil.

    • Perfect, but melts as expected so better to top it off with sand.

    • Great bio substrate for your tank
Color: Bio-Stratum Size: 8.8 Pound (Pack of 1)
Review Image by D. S. Griswold D. S. Griswold
This is great for planting and is very nice in the tank. If you pour your water in slowly, you do not have to worry about it dusting up and making your tank appear dirty, but I suggest not washing it as that can eliminate the bacteria that makes this product so expensive. Additionally it can affect the ammonia in your tank so be sure to cycle thoroughly. Value for money: Good quality and worth the price Design: Gorgeous in tank Ease of use: Easy to plant in. Plants stay put! ... show more

Review Image by Bee Bee
I have a few freshwater planted nano tanks, all 20 gallons or smaller, and I have used this or the Shrimp Stratum as the base substrate in every single one. As long as you do not stir it up too much, it keeps the water clear and does exactly what it is supposed to do. If you want to cap it with sand, you do not need to rinse it first. It will not turn the water brown unless it is handled incorrectly. Plants grow really well in it and when the nutrients eventually run out, which takes a long time, you can just add root tabs and keep the tank going for years. My tanks stay crystal clear and the plants look great. I recommend this to anyone who wants to keep live plants in their aquarium. ... show more

    • Good soil for growing aquatic plants!
Color: Bio-Stratum Size: 8.8 Pound (Pack of 1)
Review Image by Sunny Sunny
I only had the base, recommended by the fish store. But my plants started to grow more with this soil on top of the base and CO2. I did a deep research on the internet and found this product. pros: Works great if you want to grow aquatic plants in the fish tank. cons: The particle is very small, so the water gets muddy if you touch it too much. ... show more
