Planted Tank Substrate Divider
This is not only my first thread on this forum, it's my first posting. Like many others, I've been trawling the forums looking for insights and advice about getting my first planted aquarium up and running and have been very succesful to date. However, I finally ran into a subject I can't find much info about.
I've been trying to find threads related to substrate division on this site and not been very lucky. Specifically, I'm trying to learn about the use of dividers in substrate to create "zones" of plants. I've seen multiple threads concerning dividing sand from gravel, etc., but my focus is primarily on plant runners, not the substrate itself.
For example, if I'm trying to grow both HC and dwarf hairgrass, but don't want the DHG spreading into the HC section, I was thinking if I put up plastic walls within the substrate it would prevent the DHG runners from entering the HC "zone". Any runners would have to come up, over the wall and would thus be easy prey to my always hungry snips. Again, this is just an example. I'm thinking the same theory should work for foreground, midground or background plants that propogate via runners. I'd appreciate any insights you all could offer on the matter.
