ok this is simple, 5ml of sea water in the vial then put one drop at a time the vial and swirl so it mixes. Make sure you count each drop that goes in the vial, when the water turns from a blueish to yellow then stop adding drops and add up your drops. Should be around 16-18 drops for a rating from 8-9 alkalinty
dude 1 drop + .5 dkh. Do the test count your drops till it turns yellow then cut it in half and thats your alk. Alk is one of the most important tests.
