API Test Kits for Water pH & Ammonia

The pH measures how acidic or basic the water is. Both fish and plants need a neutral pH. Infections can happen because the microorganisms are not affected by pH or ammonia content. Extreme pH changes will irritate the skin and gills of the fish and negatively affect the biochemistry of plants.

High ammonia levels are one of the biggest and most common killers of fish. Ammonia causes the blood to lose its ability to carry oxygen to vital organs.
