Hanna Marine Alkalinity Pocket Checker (dKH)111
Alkalinity helps to maintain a stable pH, a vital factor for most aquatic life. Corals also need an adequate level of alkalinity in order to support healthy growth: if levels are too low, corals cannot precipitate and form their skeletons; if levels fluctuate too much or too quickly, growth can become impaired.
The more precise and stable the levels, the better the results. With regular, precise monitoring, fluctuations in levels can be quickly corrected, giving your corals the best chance of success.
Hanna Marine Phosphate ULR Pocket Checker
The HI-774 Ultra Low Range Phosphate Checker® HC (Handheld Colorimeter) provides a simple, accurate and cost effective way to measure phosphate from 0.00 to 0.90 ppm. Phosphate is an important parameter to measure in aquaculture and aquariums. Levels that are too high can lead to extensive algae growth, depleted dissolved oxygen levels, and ultimately can be fatal to many types of fish and aquatic life.
