Red Sea Alk test question (not about end color)

[donnievaz]

So the Red Sea Alk test consists of 1ml of reagent to 10ml of test water. Is there any reason that couldn't be cut in half with out skewing the results? I test alk all the time, looking to save a little $$. Seems to me that it should yield the same results but I'm no chemist.

The test kits are made to use that amount so I would think it would mess up the results. Test both the 10 and the 5ml and compare results.

You can cut the tank water volume and dye solution in half and then each mL of titrant added counts as twice as much alkalinity.

That's what I figured, thanks.
