Hey Kelly, nobody will/should make fun. If your not sure of something, you'll never find out unless to ask!!!A video helped someone mention it might be bubbles feeding into the filter. My bubble curtain is too long! I would never have guessed that without the help of this forum! I am soooo happy I joined! Now, to get myself booted out....(haha, I hope). What exactly is a substrate? From my reading I thought it was the bottom of tank (gravel and such) that held the "good and bad" bacteria. Please don't make fun, I started these tanks within the past few months, and am taking in a lot of info....
