I like this thread a lot. I am new to aquascaping, I have kept plants in my tanks for years real low tech.
It is great to have suggestions like these here, and I like hearing not everyone is following the rules to T. I most certainly threw things together willy nilly in my tank and am learning as I go. I will always keep it the way I like it not the way the "book" says as per say. I guess if I was in contests and things then I would be more technical about my aquascape otherwise I am fine with it looking good to "me" .or even just me.
