need suggestions on substrate!
hi, I recently set up a 180g tank but being a total newb and not knowing I need a specific kind of gravel for a planted tank that I want to have a carpet of HC, I got some regular gravel (big/thick grains, the popular light/dark brown stuff at petsmart), but now I realize I need smaller size substrate to grow any kind of carpet so I am wondering what are my choices here? I have heard using 'Seachem Flourite' is good for growing HC and hair grass, and 'Caribsea Eco-Complete' is another one I have been looking at but I dont like the color of black for substrate! what do you guys think I should use? will seachem flourite do the trick?
and btw can I put these on top of my gravel? I figure since I really only need these to help with growing the HC/Harigrass and the other plants are pretty hardy and doing fine right now I can get away with just putting 2" of one of these on top of my current gravel and than planting the HC/Hairgrass?
any help appreciated
