Thanks. I was hoping to find a large enough piece of DW to only need 1, but was unsuccessful. Since I'm pretty new to planted tanks I didn't want to go overboard on the plants, so with the 2 medium sized pieces in there (or 1 large if I could've found it) it covers more surface area, which I like. Also since it's such a low tech tank the plants won't grow very fast which is good for me since I don't want to have to trim them and perform a lot of maintenance.
I'm hoping to learn a lot from this setup and once I feel more comfortable I may step it up a bit.
Do you have any pics of your tank(s)?
