I got a little confused whether you were advocating cutting the amount in

Personally, the only test kit I use up by season end is pH and I'm not only
checking my stuff, but doing water tests for other ponders. In the KHA
program they suggest replacing yearly, so I'm only going for year on each
kit and the club covers my kits' cost since I'm doing other members.

If I was just doing my own and holding the kit for the supposed 2 years
(assuming it was fresh when I got it) I think I'd still have liquid left to
toss out, and I'm good about doing tests. I'd be surprised if most people
on here even have the all kits they should, let alone use them often enough
to run out. ;o) ~ jan

Unless things have changed in the last 25 years or so the ammonia test
kits that use nestlers reagent are supposedly only good for a limited
time.. the ROT 'was' 1 year so that is how often I replace mine..
(Since I invariably loose, misplace, spill or contaminate one or more
of the parts to the kit it is easy to remember to replace...)
