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.
