I inherited a nice set up that has been total neglected for 2 years just left to run. I have completely cleaned all the equipment like new again. The last thing I have to do is deal with the live rock. Not sure how to go about it. The tank had a ton of pink “leather” crap all over it and there were tons of these little green egg looking things all over. There is still lots of egg things on the rock. It has been out of the water for about 3 days now. In garage that has been hitting close to freezing at night. How do I clean this up? Is it to late? Can I use fresh well water to wash it off? We have a well no chlorine in it.
