I just put 5 lbs of black sand on top of the Floramax. I just poured it on top for now but figure it'll mix together over the next few days. I've got some rescaping to do with the plants I'm keeping tomorrow so I'll stir it up a bit. I'm hoping the light mixture will give the tears more to grab onto. I have some old river rocks that I'm going to break with a hammer. A couple 4 or 5 inch round rocks broken in half should do the trick to make a valley that flows from the back left of the tank to the center with that corner being higher than the front. Sort of like the above photo. I'm not going to order my HC until my T5HO shows up next week. It, my new dry fert, and my API master test kit all shipped today.
