What is the best way to promote coraline algae growth. I started with 10% live rock and 90% foundation rock and want the coraline algae to grow onto the foundation. Is there anything I can do to speed the process or do I just need to wait months or years for it to spread? BTW my tankhasfinished cycling and all tests show good. Ammonia, nitrites, phosphates, and nitrates are at 0, and calcium is 460, alkalinity is almost 10. I added a blue damsel yesterday and plan on getting the CUC in a week or two when enough detritus and algae form to feed them. I just want my rocks to look prettier.
