I always try to stay away from too much automation with my tanks. However, I do believe aquarium controllers and automated monitors are very important.
Options are available for testing parameters for a reef tank. You can use hobby grade test kits or an ICP analysis, a much more precise and thorough method.
The much anticipated ION Director will allow reef keepers to monitor and control Calcium, Magnesium, Potassium, Sodium, and Nitrate.
Here are my initial thoughts and impressions about GHL’s Profilux 4 controller after making the switch from Neptune’s APEX controller.
Is automatic monitoring and control of calcium and magnesium on a daily basis really necessary for a SPS dominated reef tank?
