Frequently Asked Questions (FAQ)
Q: What is salinity and why is it important?
A: Salinity is how salty the water is. Saltwater fish and corals need the right amount of salt to live. Too much or too little salt can make them sick.
Q: What is pH and why does it matter?
A: pH is a scale that measures how acidic or basic your water is. Most saltwater fish like a pH between 8.1 and 8.4. Wrong pH levels can stress fish.
Q: What are ammonia, nitrite, and nitrate?
A: These are waste products. Ammonia and nitrite are very toxic to fish. A healthy tank should have 0 ammonia and 0 nitrite. Nitrate is less harmful but should also be kept low.

A: For new tanks, test more often, maybe every few days. For established tanks, testing once a week is usually good. If you see problems, test right away.
