i have seem to have lot my Red Sea Ca Pro test kit card, their website has the directions, but no color chart i could find, can anyone using the same scan it for me?
Thanx in advance
if u have the directions then u should be fine. There are only two colors on the chart. After u put in drops A and B and let it sit a couple seconds it should be pink. Then u add one drop of A and shake and continue doing that. When the vile turns orange u count how many drops of A u put in and multiply that by 50 and that tells u your calcium level. Hope this helps.
