I get wacky results like that too. I purchased a digital PH meter for
$100.00 and problems went away.

I have a question regarding the Master Test Kit by Aquarium
Phamaceuticals.

It has 2 Ph tests, one for freshwater and one for high Ph. If I test my
water using both tests I get different readings and I don't understand
why. If
I use the freshwater test it reads 7.4, but when I do the High ph it reads
8.4
all the time anytime of the day. I believe my Ph is 7.4 because I add
baking
soda to raise the KH, but why wouldn't the high range test show 7.4 also,
it's
part of the color code. Anyone know why and what my Ph really is?

TIA
