The first step of this 2-step process is carried out in an aquarium by nitrifying bacteria. During this quick process, the ammonium levels drop while the nitrite levels increase. Since nitrite is just as harmful as ammonia, nitrite levels should be maintained at immeasurable levels. A mature biological filter should be able to keep nitrite levels low.\u003cbr\u003e\u003cbr\u003eAlso, if tap water is to be used in an aquarium, it is recommended that it be tested for phosphate, as well as silicate, ammonia, nitrate, nitrite, pH, and alkalinity.\u003cbr\u003e\u003cbr\u003eThe HI764 Checker Handheld Colorimeter bridges the gap between simple chemical test kits and professional instrumentation. Chemical test kits are not very accurate, while professional instrumentation can cost hundreds of dollars and can be time-consuming to calibrate and maintain. Hanna Checkers are accurate, affordable and easy to use.\u003cbr\u003e\u003cbr\u003eTo begin measurements, first, zero the instrument with your water sample. Next, add the reagent. Last, place the vial into the Checker, press the button and read the results.
