Usually I keep everything moving in my dip solution by gently shaking the container and tumbling the corals around. However, dipping a bunch of candycanes today caused some tissue damage on the smaller colony in the container. What can I use to keep coral dip flowing? will an airstone work? I don't have any spare powerheads for exclusive use with a bucket of dip and it's not realistic for me to handle the corals directly for 10 minutes straight without injuring the coral.
