Can I use this for dirt?

The Kit does not test for calculus.

What range of ammonia concentration do the strips cover?

As deadly as Amonia is to your fish, you would be better served using API Ammonia test drops. The strips are not nearly as accurate. Just buy the API Freshwater Master Test Kit. In my experience the none of the test strips are not accurate as the drops.

Will this item test for cyanobacteria?

No, the ph test kit will not test for cyanobacteria.

Do these measure total amonia (tan) or just free amonia?

API Ammonia Test strips reads total ammonia.

Not sure about efficiency

I aint sure it is measuring anything. Use is easy but i am not sure the band really interacts with the water in an efficient way. But the fishes are alive.

Easy to use

Set up a new tank recently and used this to monitor the water cycle changes. And it did changed and show the water parameters changes as expected. It may not be 100 accurate but certainly good enough as indicator unless you need point blanc accuracy.

good accuracy

Reasonably good accuracy for a test strip (when compared to the results of a master test kit). It's quick and easy which means we'll actually test more regularly. We will buy this again.
