For some time now, I have had issues with my kdh levels being high in my water changes. I use a 12 gallon plastic storage container to mix my water changes. I have found that if I use my kdh buffer in that container, the kdh levels are much higher then needed once mixed. I use 1/8 tsp of buffer per gallon of fresh water to bring the dkh to 9.0-10.0. If I put 1/8 tsp of buffer in a 1 gallon bottle of fresh water, it will be right on the dot. If I add 1/8 tsp of buffer per gallon in a 4 gallon water change in my mixing container, the kdh will be well over 13.0, without fail. Anyone had this issue, or perhaps I am overlooking something obvious?

Yes, RoDi water, instant ocean reef crystals, and I have to use a buffer or Kdh will be far to low.
I'm assuming you mean Dkh as in alkalinity? Maybe I'm wrong here though. Reef crystals itself mixes to I think around 11 or 12 doesn't it? Adding a buffer will make that even higher.
Yes, dKh, I just realized I did that. Lol.
What do you measure the alkalinity to be in fresh salt water, and how are you measuring it?
