There are a number of parameters you need to monitor to maintain a healthy and successful reef tank. We are going to discuss reef parameters in a couple articles not to overwhelm you guys. Alkalinty and pH are 2 parameters that should be monitorred. Your aquarium’s pH can be in the alkaline range. Alkaline is just a fancy word for basic. Marine aquarium’s pH should be slightly basic. It is recommended to be between 8.1 and 8.4. Alkalinity is how well your aquarium can resist changes in pH. Alkalinity and pH get confused quite a bit. Hopefully this article can clear that confusion up a little. Plus, if you have any more questions, the crew at Pisces Reef are very knowledgeable. Alkalinity and pH are related, but not the same. The pH of water is given a logarithmic scale from 1 to 14. The pH of an aquarium is the measurement of hydrogen of in the water given at a power. The changes in an aquarium’s pH in too short a time can cause osmotic shock in your fish and corals. Alkalinity is a complex concept to think about. Your reef aquarium’s alkalinity is recommended to be at 8-12 dkh. Alkalinity is the measure of how much acid (H+ or hydrogen ions) is needed to bring the pH to a specific level. Without getting into so much science and math, pH and alkalinity are vital to a successful reef tank. For in a more in depth discussion, speak to your Pisces Reef staff.
