Hi aquarium experts,
I am unsure if the planting gravel i bought at a succulent show is safe for my aquarium? The gravel is pretty nice looking and i would like to place that on top of the aqua soil i just bought. I have never used aqua soil before, only flourite and sand. My concern is that the gravel could potential leech mineral into the water colum. But i also figure that if they use that for the top cover with succulents and other plants, than it would be safe.
Is planting gravel ok to use? Can I place a layer of gravel on top of the aqua soil?
Thank you much!
