Contains everything you need including why and when the tests should be performed and recommendations on aquarium maintenance. Phosphate can enter your aquarium through tap water, fish waste, and decaying organics such as uneaten food or dead algae. As phosphate increases, so does your chance of having unsightly algae and green water blooms. In saltwater, phosphate can also inhibit the growth of corals and other reef-building organisms. This kit allows you to easily and accurately measure the phosphate level and maintain a healthy aquarium.

Easy-to-use professional alkalinity test kit for marine reef aquariumsAccurate measurement of aquarium alkalinity to 0.04 meq/lEssential test kit for marine aquariums, especially reef systemsAccurately measure alkalinity to maintain a stable and healthy reef environment. Easy-to-use Red Sea Alkalinity Pro Test Lab simplifies testing and boasts accurate measurement of alkalinity to 0.04 meq/l (0.1 dKH). Titration test includes full instructions, test tube, and easy-read color scale. Box converts into a mini testing station for easy access and convenient testing.Alkalinity is a measurement of the buffering substance bicarbonate and carbonate present in seawater. The alkalinity of natural seawater is approximately 2.5 meq/l. The buffering substances are depleted from the water on a regular basis as corals and invertebrates build their skeletons/shells - also as the acidic waste produced by fish is neutralized. A high, stable alkalinity is essential to maintaining a stable pH and to ensure a healthy growing reef.Please click on "More Information" for instructions.

Easy-to-use iodine test kit for marine reef aquariumsTests within 0.01 ppm accuracy total iodine level in aquariumsEssential test kit for reef hobbyists that supplement with iodineEasy-to-use iodine test kit measures total iodine levels in reef aquariums. The Red Sea Iodine Test Lab measures total iodine as iodide and iodate and the result is accurate to 0.01 ppm. Regular testing with Red Sea Iodine Test Lab is essential for reef aquariums especially if iodine supplementation is employed. Includes full instructions, test tube, and easy-read color scale. Box converts into a mini testing station for easy access and convenient testing.Iodine has an important biological function to macroalgae, anemones, and soft corals, as well as enhancing colors and preventing coral bleaching. Concentrations of iodine above the natural level can be harmful to the delicate tissues of corals. Regular testing makes iodine supplementation more effective and safe. Iodine levels should be kept at 0.06 ppm and never exceed 0.08 ppm.Please click on "More Information" for instructions.
