So last night i tested some water i had previously placed in a water tight container from tuesday. On tuesday i got a reading of 7.8dkh. Testing that same water sample again last night, i got a reading of 10dkh. This tells me i am absolutely doing something wrong, or my test kit is bad (most likely user error).
At this point i have decided i cannot trust my collected data, and i cannot trust myself using the red sea kit. I went ahead and ordered the hanna checker dkh and calcium kits. I also ordered the specific hanna water for the ca checker due to reading reviews of people saying they are not accurate without using it. I will re start testing once everything arrives in a few days.
Mg has never changed at all in any of my tests, it has always read pretty high at 1420.
