When used with the Focustronic Mastertronic, 5 sets are required to load 20ml into 2 vails.
(ranges from 0 to 4 mg/l, but is best above 0.2 mg/l.)
Colombo's phosphate test is simple to use, in part because of the straightforward usage instructions and the test's readability.
For corals and algae to grow, the phosphate level must be regularly measured.
As phosphates are nutrients for algae and corals cannot survive high phosphate levels, this must be measured.
40 tests maximum per set when using a manual
