Because I can....
You are set then. You have already seeded the rock and now you just have to wait it out. I used the aquamaxx dry rock and had to weight a good time. You have any thing in the tank? CA and Alk are a little steep. I had the most growth of coralline around 450 CA and 9 Alk.
I am learning patience too. A good quality to have, my students teach me it
This ^! Given enough time and ideal conditions, you will want it to stop growing once it starts. I scrape my back wall weekly to get it off. I let it float around and stick to whatever it hits. I started with the same aquamaxx dry rock and they are 90% covered. Less than six months.
Please wait. You do not need to seed any more or dose to insanely high parameters. Keep up with your normal husbandry, set an aggressive light schedule, and it will grow.
