I'm having the hardest time growing Corralline Algae. About 2 months ago, I noticed small spots on the walls of my 75g Hexagon tank. I even saw some spots on a few pieces of my live rock. I went on vacation for a week (Thanksgiving) and returned to a tank full of Red Slime algae. I did an immediate water change (appx 40gallons), added some API algae remover, treated it daily for about 2weeks. The red slime came back. I went out and bought a RO
unit to clean my water up BEFORE adding it to the tank. A month later, the red slime is somewhat under control, but I have lost every bit of my Corralline. I went out and bought an API Reef testing kit, and found out that my Calcium level is 300ppm, KH
is 9, and my Phosphate level is .25ppm. I realize that inproving the Calcium is my top priority, and decreasing the phosphate is right behind that. I have part 1 and part 2 of Ocean's Blend that I will be adding to my tank daily. To all those that grow Corralline, how long can I expect to see some growth once the above parameters are within range?
