Hello,

I was wondering if you guys could recommend a probe or meter which
tests the water for the following:

- Nitrite
- Nitrate
- Ammonia
- PH

Any ideas? I hate these damn test kits!!!

I have inquired about such things in the past and found that nobody has
made electronic tests for the first three. I may have found poor
information, or the facts may have changed since then, but that was what I
found at the time.
