I just recently bought a red sea alk test refill because my orginal/first ever bottle was running low. When I used it today, the color was more yellowish than red. This also affected my alk reading as it was near 10dkh when just last week it was 7 with the original test. Can anyone help?
Thanks and happy Reefing
