Hello,

What are the correct parameters for coraline algae growth? Thanks

If the calcium is in the 350-450 ppm range and alkalinity is in the 7-11 dKH range, that should be enough. Keeping magnesium around 1260 ppm or so is important, but it's very rare to have a magnesium level that is too low. 1100 ppm is fine, for example, in my experience.
