Build a mature-looking reef with stable chemistry and practical coralline growth tactics.
Grow coralline algae faster by keeping alkalinity at 8 to 9 dKH, calcium around 420 ppm, and magnesium near 1350 ppm, while avoiding parameter swings and over-scrubbing rock. A balanced clean-up crew with snails and urchins can help it spread, and steady chemistry is the biggest factor.
Coralline algae is the pink-purple crust that signals a maturing reef tank.
Add balanced grazers like snail and urchin clean-up crew members.
