No coraline growth

Your parameters are ideal for coralline growth which is odd...other then maybe a Mg level of 1480. Seems a little high.
what kind of lighting?
I used a whole bottle of Coral Vital by Marc Weiss over 3 months when starting my tank. My coralline growth is insane.
I do know high phosphates will inhibit its growth. Do you run GFO? You didnt list your phosphate levels.

Coralline algae does not like bright light.
Try lowering your settings.

same thing going on here too. when i had halides corraline was everywhere.. now with china leds it hasnt started growing in tank for about a year. starting now on glass and just a bit on rocks. although i had it covering in layers on the glass divider in sump with a crappy light.
since i raised the mg (1500)ive noticed it growing more now.

Same thing going on here as well. Tank is about 8 months old... no corraline on the glass.. or very little, but it'll grow on anything that's not the glass walls; filter intakes and outputs, mp-10 wetside, heater, etc... just not the glass. FWIW i'm using a 4 bulb T5 fixture about 6 or 8 inches off water surface, and have ample light to grow some SPS frags...

Like uncle salty mentioned coarlline wont grow well on surface that are getting blasted with high light. Some people have been surprised when they have lifted a rock from they're display to see the entire underside of a rock covered in coralline. It was because of the light.

If you want coralline, standard T-8 flourescents are the best way to get it.
A mixture of 10K and actinic, and coralline will grow like crazy.

I would drop to 50% white and 60% blue.
That's just what I would do.

Actinic blue light actually drives photosynthesis as much or more than white light does.
Light spectrum is measured by the Kelvin scale. Natural sunlight on a clear day registers at 5500 Kelvin degrees. Kelvin temperatures less than 5500 become more red and yellow and the higher the Kelvin temperature the more blue the light is. Photosynthetic invertebrates should be kept under lamps rated at or near the Kelvin temperature where the invertebrate was collected. Shallow water species should be kept under 10000K lamps while deep water species would prefer 20000K lighting. Longer photoperiods can not compensate for incorrect light spectrum or intensity.
Actinic lighting peaks in the 420 nanometer range and emits a fluorescent blue light and is usually used as supplemental lighting. Not only is actinic lighting beneficial to photosynthetic invertebrates, it is also aesthetically pleasing to the eye when used to supplement "daylight" lighting.

Just curious...why would you want coralline on the glass? Makes sense on the rocks but the glass?

I think hes just saying its a byproduct of his light.

once it starts growing, it grows EVERYWHERE... on the glass, on my magfloat cleaner, on the powerhead, etc... it's a PITA to clean.
not a fan of coralline algae
