Conditions in aquarium water naturally change over time, so it becomes necessary to regularly test your tank water to make sure it is healthy and stable. Bulk Reef Supply sells a variety of test kits to best fit your needs - Elos, Red Sea, Salifert and Elos master test kits that include essential tests for your aquarium type: pH, hardness, ammonia, nitrite, nitrate and oxygen — all necessary factors to that need to be maintained to ensure a healthy and thriving tank.

Salifert Test Kits feature distinct and noticeable color changes during normal use. When you compare price, quality, and ease of use, we at BulkReefSupply.com believe that Salifert is the best value in tank test kits. ELOS AquaTest titrimetric test kits have a very high accuracy rate thanks to elements that include calibrated lab droppers with consistent and predefined drops of 0,03 ml each, and NIST (National Institute of Standard and Technology) certified samples to validate reagents.
