Nutrafin's pH Wide Range Test (4.5 - 9.0) measures the general range of pH in fresh or salt water aquariums. Most fish species require specific levels of pH to survive. By determining whether your aquarium water is acidic or alkaline, you can create a natural habitat for your fish.

The kit provides up to 100 tests and includes:

• One 10 mL (0.3 fl oz) Bottle of pH Wide Range reagent
• One Glass test tube with cap
• One Pipette
• One Lab base
• One Instruction booklet
