Ideal for coral reef tanks, plus fresh and salt water aquariums. Also natural, waste, agricultural and drinking water. With its high accuracy and low level detection at the touch of a button - the HI-713 Phosphate Checker is assisting marine and fresh water fish enthusiasts with the daily care of their tanks.
Phosphate directly inhibits calcification by corals and coralline algae - even at low levels. The health of plants in freshwater aquaria will also be impaired by raised levels of phosphate in the water. Phosphate naturally occurs as waste decomposes in coral reef, salt and fresh water aquariums. While it does not directly harm fish when levels are high, resulting green algae growth can deplete the oxygen levels in water. Corals can lose their colour due to the effects of brown algae.
The optimum phosphate level - particularly for reef tanks - is often quoted as zero or 0.05 mg/L (ppm).
With its ability to register the presence of phosphate in salt and fresh water at extremely low levels, the new Hanna Phosphate Checker offers a real 'must-have' addition to the fish lover's equipment chest.
Key Features:
Test Results in 4 Easy Steps
Quick results from a single button in 4 easy steps. First zero the Checker with an empty vial inside. Next place a 10ml water sample inside the vial and add the included reagent. Return the now full vial to the checker. Press the button and read the result.
More Accurate than Chemical Test Kits
The checker uses an adaptation of Standard Method 4500-P E. The result given is accurate to ±0.04 ppm between 0 to 2.5 ppm. Most chemical test kits on the market are only accurate to ±0.1 ppm.
Hand-held Portable Design
Small compact size with a single button and powered by only one AAA battery (included) makes these Checkers from Hanna Instruments incredibly versatile and portable. Perfect for aquarists, aquaculturists, fish keepers, and even scientists in the field.
