How important is it to have fluorite in a planted tank? How much will it help plants grow, and how healthy will they be without it? Unfortunately, I mixed crushed limestone with it, which messed with my water, so I have to buy more or pick out all the limestone piece by piece. If I DO use it, should I replant everything, and do major gravel shifting, or is it ok if I just push the gravel with nothign growing it it aside, throw the fluorite in that space, and cover it up? Will the nutrients get to the plant that way?
