Against my original plan of not adding any of my existing rock to the new system, I am now thinking of doing that. I have some live rock coming from the keys next week, so I wanted some opinions on this.
My current rock has been established for around 5 or so years. Started off dry, and I have dosed Cipro, Chemiclean, Fluconazole, Vibrant, Bayer, and Ivermectin through that time frame. The existing rock has bubble algae and aiptasia, which I know will be next to impossible to ultimately avoid, but I would like to if I can help it.
I have heard of others dipping their rocks in kalkwasser to kill all life on the outside of the rocks but preserve bacteria on the inside. I was thinking of scraping off all bubble algae and removing corals, then giving them a bath in kalkwasser.
What does everyone think of that idea? Is it worth it to help seed my tank with bacteria, or should I just add the rock from the keys and move on? If it is worth giving them a bath in kalkwasser, then does anyone have an idea on strength and for how long?
