When the magic occurred and Coralline Algae started in my tank, it was like love, there was no doubt.
In my tank it grows most in areas of flow. Likes glass areas where the return is directed, and the overflow slots, and the wave maker.
Red Tuxedo Urchins will literally remove all the Coralline Algae except where flow reduces their grazing.
I dosed two bottles of Coralline Algae in a bottle without result.
I believe it was the addition of All For Reef that made the difference even though I use Tropic Marin Bio Atif salt. I have this suspicion that rampant and visible coralline algae growth is the result of elevated dkh and normal levels won't produce the rampant growth. An artifact of reef keeping.
Might not be dkh - it might be just calcium - I know my calcium levels are REALLY high.
Like plants, CO2 levels have a big determination of plant growth and biology, high plants thrive, low annuals can't complete their life cycle in a season, too low at around 250 ppm, they simply die.
Coralline algae and even snails will grow much faster at elevated levels. The snails were adding shell at a noticeable rate once all for reef was being dosed.
Or coarse acting on a single data point would be a ...
