Keeping plants down in substrate
I'm having a little problem with some of my plants staying plantged down in the substrate. I plant them and put the roots in but frequently the substrate doesn't hold them down well enough and occasionally they just float to the surface randomly. Is this a problem other people have?
The substrate in my tank is from Aquariumplants.com and is a fracted clay substrate. It seem pretty lightweight to me but then again I don't know how it would compare to Eco-Complete, Fluorite or Onyx. Any recommendations on how to work around this?
