I have been browsing through various resources recently on the ideal water parameters for accelerated SPS growth and have found contradicting results. I am looking to the Canreef members running primarily SPS or Mixed Reef setups and are having good success with coral growth and colour. There are the average parameters that are listed for a successful reef tank, however I'm looking for what is working for your tank and what you have altered for success.

The Big 3 - Calcium, Alkalinity and Magnesium as well as Salinity, PH and Temperature. Please share your parameters (what test kit used) and your experiences with any fluctuations.

I currently have a mixed reef setup and have recently started adding more SPS frags in my 75g tank. My current water parameters are:

• Calcium - 500 ppm (API).
• Alkalinity - 12 dKH (Hagen).
• Magnesium - 1400 ppm (API).
• Salinity - 1.025 (Sybon Refractometer).
• PH - 8.2 (API).
• 78 degrees Fahrenheit (Digital Thermometer).

Looking forward to see what it working for the awesome tanks out there!
