I don't plan on getting any fish or coral until the end of April or May. Two questions, should I do a water change in the bucket that I currently have the rock in? When I move the rock into the tank should i use new salt water or should I use the water that the rocks have been in for the talk 4 weeks?
I'd get readings on the bucket water before deciding whether or not to use. If there was a lot of dead organics in the rocks after their six month dry spell, your current water may have high levels of nitrate and phosphate, which means, add light and you'll have algae. If the water has high readings in either of those areas, I'd use new water.

FWIW,
Kevin
