Gives it the mature look of a well established tank but everyones got there preferences.
I like the idea of scrapping the back during the first year to seed the rocks will try this on my new tank.
Very true. When the powerheads, overflow and return pipes are getting coated then having the back and even a side covered in coralline really does make it all match the rest of the tank.
The only thing that can be lost is the sense of depth that certain black, blue or white backgrounds can give to a tank. A tank can look smaller when the back is encrusted and brightly lit, like a coral cage. I made a shade for a tiny 10 gallon reef I ran for about 5 years just so the back, which was solid coralline was much darker than the rest of the tank and it added a great look of depth that it was missing. The shade also seemed to make the coralline grow thick. It didn't work on my 30L reef, though. That tank just had to be scrapped down to give it the right effect. I love how there are so many ways to adjust the feel and look of a reef!
