What type of substrate should I use for aquatic plants?

you can use sand or gravel that would be fine if you want to you can get flourite or eco compelete. i use flourite and i like it very much for plants then i got a med tech set up for my tank with t5ho lighting and pressurized co2. i would suggest to stay away from box stores for plants they are mislabeled with wrong plants and not true aquatic plants.you can go here a href="http://www.aquariumplants.com/Aquarium_Plants_s/1.htm" rel="nofollow"http://www.aquariumplants.com/Aquarium_P…/a click on the beginner or low light plants. i have gotten some plants from them and they are great, or go to fish forums like this one a href="http://www.aquariacentral.com/forums/" rel="nofollow"http://www.aquariacentral.com/forums//a they have a section were you can buy live plants from people who grow them in there own tank i got a lot of mine from this place also at a great price on different plants
