I wanna get a really nice planted tank setup or at least add plants to my tanks im setting up right now......and I dont have the cash (actually im just super cheap) to buy the super expensive, eco complete, or whatever, i was wondering what cheap alternatives could be used for the different layers needed, im gonna put black gravel on the top just cus i like how it looks and I'll use fertalizers and plant food and whatnot i just dont wanna have to spend like 40 bucks on a bag of substrate.....im also gonna get a nice diy co2 setup
