Well, it wasn't very noticeable when I was first setting it up because of the cloudy water (because of the sand I used) but now that I have got the water cleared up nicely I can see that the inside of the front panel is almost completely covered with what looks to be water spots. I have a mag-float and I have been over the entire tank multiple times but it doesn't help at all (granted, on 15mm glass the mag-float doesn't have a ton of strength, but plenty to get anything else that's on the tank off). Is there anything I can do to try to get rid of this while the tank is up and running. I don't think breaking it down to clean it right now is an option.
Thanks for the help!
