MultiTest - Marine pH/Alkalinity - 75 Tests

Seachem MultiTest - Marine pH & Alkalinity is a professional grade water testing kit designed for use in delicate saltwater and high pH freshwater aquariums. The kit will accurately test the water and measure pH and alkalinity levels to ensure a healthy, stable aquatic environment. In ideal conditions, marine water should present a pH level around 8.2-8.4, but tanks that have been dosed with limewater may show increased levels as high as 8.6. Natural seawater has a total alkalinity of 2-3 meq/L, but for the best most stable conditions, home aquarium water should feature a total alkalinity of 4-6 meq/L.

This efficient and effective test kit features an exceptionally unique dye that boasts a noticeable color change between the levels of 8.0 and 8.3, making it the easiest kit on the market to identify values that fall within that critical range. It is suitable for marine or brackish water only. Conveniently, Alkalinity may be read from the same sample in 0.5 meq/L increments. Seachem MultiTest also measures the values of total alkalinity. Total alkalinity is a measure of the essential carbonate, bicarbonate, borate and hydroxide content of the water, expressed as the acid neutralizing capacity of the water in meq/L (milliequivalents/Liter). The expression of alkalinity as meq/L is the most useful and understandable way to express this property of the water to resist change in pH.
