Why pH Matters
pH measures how acidic or alkaline aquarium water is. A pH of 7.0 is neutral, above 7.0 is alkaline, and below 7.0 is acidic. Different fish require different pH levels to stay healthy, so regular water testing is important.

When to Use
Use when aquarium water testing shows that pH is too high and needs to be lowered.

Usage Reminder
Test aquarium water regularly and always follow the dosage instructions on the product label.
