Recently pulled out a rock that was being taken over by zoanthids. It started to creep up on a chalice and other group of zoanthids in the tank so I thought it would be best to remove said rock and euthanize the zoanthids spreading across it. I placed the rock out in the sun and now have two questions.
- How long should I leave the rock out in the sun? I figured around a week for them to completely die out but I haven’t ever done anything like this so I have no idea.
- Should I take precautions before putting the rock back into the tank? I don’t know if there will be some sort of biological die off that would spike my ammonia but I figured rinsing the rock after its done drying would possibly get the job done.
