Salifert Potassium Reef Test Tunze Oil slicks reduce the amount

Oil slicks reduce the amount of gas exchange at the water surface and the air above

Rowa Carbon Contains extremely low levels of Phosphate

Spherical for optimal hydrodynamics

MICROBE-LIFT/TheraP has a hydrogen sulfide odor

Directions for Testing Ammonia Levels

Salifert Potassium Reef Test Tunze Oil slicks reduce the amountPotassium concentration in natural seawater is approximately 400 ppm. Many aquarists have reported that a low potassium value reduces colors in corals. This can be corrected by increasing the potassium value to the normal natural concentration. Now you can accurately measure this value with the new Salifert Potassium Reef Test kits. Test resolution of 10ppm ranging from 0 to > 470ppm.
