Colombo’s phosphate test is easy to use, partly due to the easy instructions for use and it is also an easy-to-read test.
Regular measurement of the phosphate level is essential for corals and algae growth. This must be measured because corals cannot tolerate high phosphate levels and they are nutrients for algae.
