Significantly decrease the risk of algae outbreaks.
Keep waste and particles suspended longer so skimmers and filters have a better chance of removing them.
Prevent toxic pockets from forming in hard to reach areas.
Keep debris from collecting on corals.
Keep food suspended longer so you can add less food.
Increase the chances of long term healthy tank success.
