I've been cooking some live rock for the past month or so. It's been in some Rubbermaid bins with a powerhead to circulate the water. The lids have been on, too, to keep the light out. Am I doing this correctly? I have some other questions, too .........

1. I'm doing a water change right now, and thought I'd use the water I'm taking out of the system to replace the water in the Rubbermaid bins. Good idea? Bad idea? Doesn't really matter?

2. I've been cooking it to try to get rid of some Aptasia and Bubble algae. I don't know if I want to put too much more rock in the display tank, though. I'm going to look for the nicer pieces and was thinking about putting the rest in the sump or fuge. Which would be better?

3. If there's still some Aptasia or Bubble algae on what's left, will it hurt anything putting it down there?

I'm going to finish the water change and swap the water in the tubs. Then, I'll check back to see if anyone has any answers. I'm sure changing the water in the Rubbermaid bins won't hurt anything. Really looking for answers to #2 and #3. Thanks in advance.
