I used to think this way, but think differently now that I changed my tank. With less rock, I can now have better flow through it and better circulation all together. Plus, my tank looks much nicer. Jeff, to answer your question, I love Marcs rock. I have one giant piece in my tank and will get more eventually. But I would go down there, pick pieces out, and go more by what looks right than weight. He has some huge pieces (at least he did when I was looking for some) that might make you think of a totally different layout for your tank.lactrain said:... I dont think you could have too much

I've got 100 lbs in my garage. You're welcome to come by and have a look and weigh a few pieces if you want, to get an idea of how much you'll need.
