Coralline Purple Algae
Ok, so coralline is considered a very good algae to have in your saltwater tank. We had added several coralline encrusted live rock to the tank, which means it is now growing everywhere! This does include the glass. I am having a bit of a tough time keeping up with it on the glass (which means some areas are probably just going to be purple forever). Scraping it off of the glass is also supposed to help the coraline growth throughout the rest of the tank.
One of the main benefits of coraline algae is that it helps keep bad algae’s from growing (too bad it doesn’t really grow on the sand, as that is where all of the bad algae likes to grow and takeover everything).
What is interesting is that everyone wants coralline algae because it is pretty and beneficial to your saltwater tank’s ecosystem, I just wish there was a better way to manage the growth on glass at the front of the tank.
If anyone has any tips or tricks on how to keep the front of the glass clean I would be happy to hear them. I try not to have my hands in the tank too often, so going at the glass with a razor blade does not appeal to me.
