And a hanna

I trust red sea calcium..that's about it because it's consistent but reads about 20-30ppm low. Not familiar with tropic Marin test
But If hanna is saying 11+dkh and tropic Marin says 10dkh....its probablt not 8. Are the test kits expired ?

When you get discrepancies like that, give every cuvette a good thorough cleaning in a mild acid solution (Vinegar, lemon juice, citric acid) and dry everything before testing again. You'd be surprised how much this can affect the reading.
