scaping coraline off the back glass?...

[thebigblue]

i notice that some people seem to scrape the coraline off the back glass...im starting to think i like this look...

is there any benefit to keeping it on?...

from a post a couple years ago...

"If you have your back glass covered with coraline algae aren't you increasing the amount of calcium and other nutrients that your tank needs?

Coraline algae needs calcium and alkalinity in the saltwater to thrive and I would think that keeping the coraline on the back glass would be taking those needed chemical properties away from the corals that we are trying to keep. This shouldn't really be an issue for those that use calcium reactors but those that are using two-part supplements or other products to keep the Ca/Alk balanced would need to use greater amounts to keep up with the demand."

then again -the corraline is competing for other nutrients as well-nutrients that may otherwise be used by less desireable algea.

additionally -problem algea will have a harder time growing on top of corraline -and the more you have the faster it spreads.

if i had a blue background id keep it clean.black looks better with it
