Phosphorous (as phosphate) can be introduced to aquaria through feed, decaying plant and animal waste, and even tap water, so it can quickly become so abundant that it becomes a nuisance. Phosphate is a driving factor in excess algae growth, so it is important to keep levels as close to zero as possible. The HANNA HI 736 Checker®HC bridges the gap between simple chemical test kits and professional instrumentation. Chemical test kits are not very accurate and only give 5 to 10 points resolution while professional instrumentation can cost hundreds of dollars and can be time consuming to calibrate and maintain. The HANNA HI 736 Checker®HC is accurate and affordable. This Checker®HC features an accuracy of ±5% of reading and uses an adaptation of Standard Method Ascorbic Acid. The contoured style of this Checker®HC fits in your palm and pocket perfectly and the large LCD is easy to read. The auto shut-off feature assures the battery life will not be drained if you forget to turn it off. The HI 736 Checker®HC is extremely simple to use. First, zero the instrument with your water sample. Next, add the reagent. Last, Place the vial into the HI 736 Checker®HC, press the button and read the results. It’s that easy.
