Questions & Answers

Are there any advantages to using this for freshwater ?

It does not appear to have a fresh water version, I believe the one I have is only for salt water.

This can be used for fresh water aquariums, right?

In short, yes. Fresh water aquariums and salt water aquariums both suffer when nitrite levels are high. Decaying uneaten food on the bottom of the tank which may even have been buried by sand and gravel is one of the causes of high nitrite levels.

You can do so many tests before needing to do more, but I cannot find a figure. What is the maximum number of tests that can be performed before more refills are required?

This was bought without reading the box, and I assumed it was for

They give very precise results when the tests are properly performed and readings are consistent from one to another, but I would recommend using their lab grade water as my RODI shows 0 TDS but gives different results than theirs. The aquarium water sample is also extremely small compared to the base solution, so any error in measurement has a drastic effect on the results.

I appreciate it

5/5

Does the job

5/5

This is a pretty straight-forward process. I can only say what more can be said with some patience and practice. She wants seven more words and now she has.

This would be nice if there was an explanation of how it should be used

5/5

The interface is intuitive. Rather than keep buying test powder once the sample you get with the meter has been consumed, you can just buy these little packets. I find that to be a little.
