Re: High KH on new tank

FWIW Marc the Salifert kit is accurate to well above the instruction sheet.

you can add more then a full syringe (of the reagent) (up to 2 maybe more)
and just multiply the total used by 16 if you used 4ml of tank water and 2
drops, or by 32 for 2ml and 1 drop.

example:   2ml tank water w/ 1 drop KH Ind and it takes 1 full syringe and
you have 0.8 left in the second......you used 1.2, so 1.2x32=38.4 dKH

that's how I've been doing the Ca reactors I have setup and its as accurate
as the much more $$$ high range kits IME.
