A while back azn_fishy55 posted some advice about HC. He warned not to let it get to thick as the bottoms can start to rot away, eventually causing the plant to float to the surface. He was right. I have had a carpet of HC growing in my 20 gallon since Jan. It was getting real thick and dense. I figured just leave it alone. Heres what it is starting to do, first on the corners, now all across the front of the tank. It's all going to float up anytime. I've learned as HC thickens up and runs out of space, it starts to grow on top of itself. As it does this, it relies less and less on the substrate for anchorage. As it gets real thick, no light hits the bottom of the plant. Sooner or later, it lets go. Moral of this story is to thin your HC out once in a while. Thick is good, to thick is not!
