Track 8 Essential Parameters with Precision
Monitor the water chemistry metrics that matter most for coral health. Set custom targets, get visual feedback, and track trends over time.
The Essential Eight
Calcium
ppmCritical for coral skeleton formation. Low calcium stunts growth; high calcium can precipitate.
Alkalinity
dKHBuffers pH and provides carbonate for coral calcification. The most consumed parameter in reef tanks.
Magnesium
ppmPrevents calcium/alkalinity precipitation. Must be balanced for stable chemistry.
Salinity
specific gravityOverall salt concentration. Affects osmotic balance and organism health.
pH
Affects biological processes and calcification rate. Stable pH is more important than perfect pH.
Temperature
°FAffects metabolism and oxygen levels. Stability is critical—avoid swings over 2°F.
Nitrate
ppmNutrient for coral coloration. Too low causes pale coral; too high promotes algae.
Phosphate
ppmNutrient that affects coral growth rate. High levels inhibit calcification.
