using a pool test kit?

[uwharrie]

I am almost out of my reagent for my Hanna Checker and need to order more. In the mean time I have a nice digital pool test kit I use for work.

It can measure total alkalinity. But not sure if that is any help in an aquarium. if so how do I convert the total reading to dkh?

or are they two totally different things?

for example I am getting 109 total Alk on the pool kit. I believe that is ppm. ( not sure if salinity affects the reading but since we also use these on salt pools I would think not)

if that is PPM than my hanna is way off. ( reagent expires this month)  as the conversion chart shows 5.9.  ( hanna showed 10)

The pool kit may be made for alkalinity for chlorinated pool water or just FW.

I ordered new reagent for the Hanna. will get IO today at the big box pet store so I can work on lowering ALK
