Hope for just gravel?
Hi all, I was wondering what you can really do with just a gravel substrate. Personally, I use soil and want to get into flourite as well for ease of plant removal, however I work at a LFS and talk a lot of customers into planted tanks. With the new affordable availability of high par lights a lot of customers would like to upgrade their lighting without upgrading their substrate. Is there any hope in having a nice planted tank with just gravel? I understand floating plants do fine as well as plants that aren't too nutrient dependent. Would it be possible for inert substrate to become lively enough for healthy and full growth of vals, sag and easier stem plants and handle par values in the medium light range?
