NO3+ from Aquaforest is a product that increases nitrate levels in marine aquariums . Problems with low NO3 levels most often affect aquariums with high coral populations and low fish populations.
The use of strong filter media, nutrient reducing agents and protein skimmers can cause a sudden drop in phosphate levels in the aquarium. Phosphorus is an important element for zooxanthellae, a photosynthetic algae that coexists with coral. Zooxanthellae are simply "starved" because the aquarium has zero phosphorus levels.
The lack of PO4 in marine aquaria makes NO3 reduction much more difficult and requires precise phosphate correction.
AF PO4+ is primarily intended for aquarists with a small number of fish or very intensive filtration. Highly sterilized water that lacks nutrients causes coral discoloration, bleaching, and significant growth retardation issues. LPS corals are particularly sensitive to levels of malnutrition. AF PO4+ lets you precisely correct phosphate levels and quickly restore the levels you need.
Accurately tests the phosphate level of your seawater.
Allows you to take around 60 measurements.
