Like many other reefers, I have used Salifert as my Alk test for years. So like me, the process is known by rote. 4ml water, add 4 drops of KH-ind, and starting with a syringe filled to 1, drip into swirling water test until the color change happens and read your value from the chart.
So if was only by stupid luck that i did notice the new kit instructs to use only 2 drops of KH-ind rather than the prior kit instructions of 4 drops. No heads up anywhere that this change had been made.
I have run several simultaneous tests using 2 drops and 4 drops (as per the older kit instructions) and the value is pretty much a whole digit out on the results. 8.3 with two drops and 9.3 with 4 drops.
I tried to contact Salifert by email but heard no response. Contacted BRS and they got right back to me with an offer to replace the kit with a Red Sea to cross check my results. I didn't take them up on the offer - did not figure it was their issue. They also mentioned that they had not heard back from Salifert in a week.
Disappointed that a test kit company wouldn't be all over ensuring that customers are not getting false readings.
Thought it was worth bringing up.
