Cheap substrate for stock lighted, planted tank
So i will be setting up a 20g L soon with moss and possibly anubias and java fern and was wondering if there was a cheap substrate that I could buy to place at the bottom of my tank. I have a 29g with the walstead method with black sand as a top and a 5g with a fluorite base and green gravel as a top. It doesn't matter if its gravel or sand to me, I just want to make sure it looks decent, is ok for the low light plants and is relatively cheap. If anyone has any ideas I would love to hear them! Thanks!
