This kit tests for Ammonia Nitrogen in fresh and salt water aquarium water samples using the Octa-Slide 2 Comparator.
The test is based on the reaction of the cationic polyquat with an anionic polyelectrolyte using Toluidine Blue O as the indicator. The color change is blue to purple. Levels are determined using the drop count method. Range and Sensitivity is 1 drop = 1 ppm Polyquat.

An easy-to-use, disposable tube method that indicates the presence of Total Coliform Bacteria. The water sample is placed in a tube containing a reagent tablet and incubated at room temperature for 48 hours. The tube is then examined for positive indicators of coliform bacteria such as color change and formation of gas bubbles. Each kit contains 44 capped tubes each containing a Coliform Test Tablet, and a set of laminated color chart and instruction flashcards.
This Biological Activity Reaction Test tests for Sulfate Reducing Bacteria. Kit includes nine tests. The change of black color indicates a presence of bacteria within that sample. Interpretation is provided with the kit.
