The two basic dry forms of chemical reagents used in test kits are powders and tablets, and then there are liquid solutions. No matter what type you use, great caution should be exercised when working with these reagents, because they are toxic chemicals! Here are some things to consider about dry and liquid test kits when making a decision on which to buy, but it doesn't hurt to try out various types and brands.
About Dry Powder Reagent Test Kits
Dry powder reagents are time dated. Check expiration dates, as inaccurate readings result if used past these dates. Store reagent packets in a cool place, otherwise they may prematurely expire. Tests that have multiple steps contain equal amounts of reagent packets. The benefit is that you don't run out of a one reagent before the other. For dry powders, look for test kits that have wide mouthed testers.
About Tablet Reagent Test Kits
This easy to use tablet reagent test kit line from Aquarium Pharmaceuticals is very popular amongst saltwater aquarists that maintain fish-only or fish-only with live rock systems, and often are chosen by reef keepers for testing basic water parameters. Kits and tablet refills are available for testing pH, ammonia, nitrite, nitrate, phosphate, and chelated or free copper.
About Liquid Reagent Test Kits
Liquid reagents usually have a limited shelf life, so check for expiration dates. Tests with multiple steps may run out of one solution before the other(s), so buy a brand that readily has reagent refills available. Liquids can be less messy than powders because they are more easily dispensed into the test tube type vials these kits usually contain. Spills and bottle breakage are a possibility.
