I've tried the tape idea that I saw on some TechPB video a long time ago. Didn't really dig it as much as a cover. Now, I don't use a huge cover either. I've been using a redz tank cover that's pretty thin. For me, I don't want my tank scratched up. It cost me a TON of money and even though a cover won't really offer much protection, it's just a peace of mind thing I guess.
