Thought it would be nice if we each shared a tip that we found to make the hobby easier/better. I will go first. This may seem like nothing but whenever I do a water change on a tank. I take the glass tops off and spray them with vinegar and use a green scrubby (scotchbrite) and remove the hard water deposits. I then rinse them off with hot water and dry them, and they usually are good as new. I find if I do this often then the build up is minimal and the tanks appear much brighter. That's my tip, what's yours????
