Totally new to substrate set up. Thoughts?
Alright, I'm still collecting my equipment and looking for just the right hardscape materials. So, I've begun to think about what substrate things I'd like to work with. I've seen some pretty fine grain, super light colored (white really) sand that I'd like for the viewable portion of my tank. I'm going to mix this with some bigger light colored stones.
As for the very bottom nutrient rich layer for the plants to grow roots into I'm somewhat at a loss. I do want to get something that will be an effective nutrient base and yet not too crazy expensive. I would like some very small plants once things get up and running, so I think it needs to be fairly fine. Also I want the sand to be super light, so I don't want something that's black mixing over time. If anyone has advice about this I'd greatly appreciate it!
