德納利Deponit Mix Pro黑色

I’ve had trouble with root-based plants in my tank before, but this substrate really holds the nutrients in place under the gravel. The grain size is fine enough to let roots spread naturally without clouding the water.

My cryptocorynes have stopped melting and are actually putting out new leaves two weeks after I layered this under my gravel. The grain size is perfect for root growth without being too fine.

I was a bit skeptical about spending extra on a base layer, but the nutrient depot in this is no joke—my plants started pearling within a week. The black color also hides the substrate nicely, making the tank look cleaner.
