Thanks so much for all the responces. In regards to flow, I know things will change as I add hardscape and plants, but I wanted to see an easy way to see if I had dead spots before I really got the tank up and planted. Several of you suggested some ways that I can try. Also CO2 I will be using so having good flow will help with that as well. I know a lot of this will be testing and moving stuff around once tank setup, but thought I would ask since I saw these things on the show they were using to test flow. It was on the show TANKED. I am trying to go back and figure out what one it was on. The things they were using were nice, because if they had any dead spots, then these things that moved around in the tank would all just collect in that area.
Thanks again for all the information.
