Colonize submerged leaves in stream habitats. The ability of freshwater macroinvertebrates to flourish depends upon the properties of the water and conditions in the environment. The relative abundance and variety of freshwater macroinvertebrates can be used as bioindicators to assess the quality of the water and the effects of land use on the environment.
This Alkalinity test kit provides total alkalinity readings only, using a Direct Reading Titrator. Testing range/sensitivity 0-200 ppm/4 ppm as CaCO3.
This kit tests for Total, Calcium and magnesium hardness by using the Dropper Bottle method. All results are as CaCO3. Range/sensitivity is 1 drop = 10 ppm or 1 gpg CaCO3.
This kit tests for Nitrite-Nitrogen using the diazotization/coupling reaction to form a pink color. The results are determined using the Octa-Slide 2 Comparator. Range/sensitivity is 0.05, 0.10, 0.20, 0.30, 0.40, 0.50, 0.60, 0.80 ppm NO2-N.

An 8″ resin column (10.25″ total height) that softens up to 70 gallons of medium hard water (7 gpg hardness) before requiring regeneration or fresh resin. Model S softener is furnished in the Model AT-38 and AT-Q-38 outfits.
Help kids understand the life cycle and habitats of freshwater aquatic macroinvertebrates with this set of flashcards and manual. The 22 full-color cards feature photos of both immature and adult insect stages, and detail life cycle and habitat information. The accompanying manual contains facts on insect characteristics, life cycles, taxonomy, classification, food webs and how macroinvertebrates can be indicators of water quality.
Instructions for activities with the cards are included. The Freshwater Aquatic Macroinvertebrate: Insect Life Cycle and Habitat Flashcards can be used as an extension to the Freshwater Aquatic Macroinvertebrate: Identification Flashcards and the Leaf Pack Experiments Stream Ecology Kit.
This Alkalinity Test Kit use titrations with standard acid to the phenolphthalein (P) and/or total (T) alkalinity endpoint. Range and sensitivity is 0-200 ppm/ 4 ppm as CaCO3.
