My problem is to find the waste in the sand is hard to find. But as you do, I like both mediums. Do you think plants can find nutrients easier in gravel or sand¿ Oh and what a great and clever name have o Great Swami of the Finned Ones who came before.
Haha, thanks.
As far as the plants, for a serious planted tank I think a specific planted medium like fluval stratum would be best. Eco-complete is a good option too, though it is inert and is basically just lava rock, it has various sized grains so that larger pieces end up on top, and finer bits go to the bottom, which is supposed to be better for roots to spread. My high-tech planted tank uses eco-complete. Have used the fluval stuff (shrimp substrate really) in nano planted tanks and thought it was great. Large-grain gravel can be difficult for plants to root in, but for plants like anubias and cryptocorynes I have found it works fine. Although fertilizer tabs may be necessary when using "normal" substrates to achieve good growth.
