Red Sea Max 130D - Nitrate Level Monitoring; pH and Alkalinity Monitoring; Salinity and Specific Gravity

45
User Manual
Check pH and alkalinity, especially if you use calcium additives
regularly. If pH drops, take corrective action by reducing feeds,
adding buffer supplements and increasing water changes.
Salinity
Check salinity and specific gravity.
These recommendations follow years of aquarist experience,
but you may get slightly different figures from other experts.
To clarify the basis for each recommendation, a brief description
of each parameter's importance follows the table.
The first chapter discussed water temperature and salinity. To
monitor the other parameters, the Red Sea MAX Starter Kit
provides you with the Red Sea Marine Lab, consisting of test
kits for the following:
 Ammonia
 Nitrite
 Nitrate
 pH
 Alkalinity pro
 Calcium Pro
 Magnesium
Red Sea also offers test kits for phosphate, silicate and iodine.
Contact your local Red Sea dealer for details.
pH
Several factors contribute to the importance of monitoring your
marine aquarium's pH level. Chief among them is that aquatic
organisms thrive only within a certain range that varies from
organism to organism. Changes in pH affect fundamental
processes in many marine organisms, such as calcification, or
the deposition of calcium carbonate skeletons.
pH levels should remain in the 8.2-8.4 range for a reef
aquarium.
