FAQ: I need to increase my KH to hold my pH steady. Will Seachem Neutral Regulator® or Alkaline Regulator™ increase my KH to hold my pH steady?

Neutral Regulator® and Alkaline Regulator™ are phosphate based buffers and will not increase your KH. To increase KH, you will need to use Alkaline Buffer™, which is a carbonate based buffer.

That said, often so-called "KH" test kits are actually measuring "total alkalinity", not KH.  Neutral Regulator® and Alkaline Regulator™ will increase your total alkalinity, so do no the alarmed if your "KH" goes up - it is likely that your test kit is simply misreading "total alkalinity" as "KH".
