adddo - got my camera back yesterday, so I will post a few more pics in a day or two.
hceiv - no UV, no ozone (well maybe ozone for 4-6 hours 1x a month with an enaly I bought years back just to try it).
Rory3 - I never let the coraline get that bad as I feel it takes away from the clean look. Coraline also absorbs light rather than replecting it back into the tank which leeps it looking bright. My maintenace is to use my magnet every day to clean the front and side panels. As s result I only use the scraper once every 2-3 months on the glass. I also keep the back panel clean. Easy to leave this accessible when you have a 36" wide tank. Last thing that makes it easy is that the tank is not tall.
