Thanks guys, the anchors were for two reasons, the first is that I'm in the planting stage and floaters annoy me especially with a quartz sand cap. I'm already considering changing the cap under only the plants to Eco or the oil absorption material Jeta mentioned to help with rooting.
The second reason is that this is a cichlid tank and I eventually will have some angry fish try to uproot some plants. I've made it very difficult to get to the bottom of any plant, but it's not a matter of if, but more like a matter of when and those anchors may not only help to anchor them at that point, but they may hold them steady early on to quicken the roots digging down. (especially till I stop digging around to add the initial plants)
