Hi everyone, just wanted to discuss whether sand is better for capping a soil substrate. Having used both I must say that for some reason sand seems to yield better results for me.
For example I got a Tropica pot of Lagenadra and put some plants in the gravel substrate and some to the sand one. Both tanks have the same type of soil underneath and are both low tech. While the plant in the gravel substrate has all but melted, in the sand substrate is growing huge. Cryptocoryne Nurii also seems to prefer sand.
Is it possible the sand locks in the nutrients better ?
