I'm not sure as it depends on a lot of factors. I was just pointing out the fact that in one line you said clear is good because it doesn't stand out, and in the very next line you said a con would be that algae will eventually grow on it (which would make it stand out). I agree with your "Con". Algae will eventually grow on it and make clear stand out. Probably slower if you have leds with optics, since less light will hit the seams.
