This stuff was originally designed for low-nutrient systems, per a rep at Seachem. If you are not running a low-nutrient system then this may be more than you need. Aside from trace, it has aminos and also a type of alge which may add unwanted nutrients to your tank. If you're looking for trace and you do not have a ulns or even low nutrient systerm, then you might want to look into Seachem's Reef Trace product. This will add the things you want to dose without adding extra nutrients to your system. If your nutrients are anything greater than zero then this stuff will likely "Fuel" algae growth.
