I almost forgot. I took pictures of 3 corals before I started that I can use for comparison. I'll take more pictures tomorrow and see if we can find some noticeable growth in a week.
Good idea. Progression pictures always tell the truth.
so once you put the kalk in the reactor do you turn the reactor on right away or do you have to wait 24 hrs?
After you put the kalk in, you want to mix it for a bit first, and then its best to let sit for a while. I never stick to the 24 hour waiting period, but I'd at least let it sit for 8+ hours before it starts putting lime water into your tank.
