Welcome to the Reef Chemistry Calculator Site
There are four versions of the calculator you can use.
The two traditional versions; one in Spanish, provide for a quick consultation for users fully familiar with Reef Chemistry.
There is a smaller simplified version that can be accessed via PDAs or cell phones. To do so, direct your device browser to http://reef.diesyst.com/cf/chemcalccf.html
The flash version; which require Macromedia Flash Player Ver 6 or higher, has features that can compare your actual and target levels with the recommended ones as well as provide possible actions for correction depending on your system circumstances.
The Flash version will also generate a chart that can be printed and used as reference for future additions without the need of the Internet. If you do not have the player installed, you can get it by using the link below. Enjoy!
