The ultra-small-scale phosphate checker Hanna (0 to 0.90 ppb) is the right choice for those who need to measure phosphates in marine aquariums and are looking for the accuracy of professional instruments combined with the convenience of simple chemical test kits. Checking the phosphate level is a common practice for saltwater aquariums and provides important information about the chemical composition of the water, which is useful for ensuring the long-term health of the corals.
Excessive levels of phosphates can prevent the calcification and growth of many coral species, particularly those known as SPS (Small-Polyp Stony).
Furthermore, high levels of phosphates can lead to the growth of harmful algae inside the aquarium, which could deprive corals of light, nutrients, and space, compromising their long-term health.
The HI774 Checker® HC (handheld colorimeter) is a simple, accurate, and affordable instrument for measuring phosphates in marine systems, including aquariums.
Phosphates are an important parameter to measure in aquaculture and aquariums; excessively high levels can lead to excessive algae growth, deplete dissolved oxygen levels, and ultimately be fatal for many types of fish and aquatic organisms.
- Easier to use and more accurate than chemical test kits
- Dedicated to a single parameter
- Small size, great convenience
- Ideal for: aquariums, environmental controls, aquaculture, water quality
