Well, just got in from walking around in the woods behind my house. I found an interesting piece of an old root for a tillandsia planter, not too big. There are a lot of vines, hanging from the trees down here, not sure what they are, but if I can figure out what they are, I'll use a couple pieces. I know it's not Kudzu...Bill I use a 6700 Kelvin lamp over my sump to help my Chaeto grow, can't understand why'd you NOT have algae. In my dealings with it, it's fairly EASY to grow and grow and grow...
