Okay so I recently started this tank, 40 gal AIO, I built the structures that are white still myself and it was dry rock. Then I know someone local to me who also has a tank and asked him for some cycled rock, because the other tank I have is only a 16 gal and I couldn't spare any live rock from it. So he gave me some rocks, I scrubbed them and placed in the tank to help with the cycling and biome building/cycling. I haven't turned the lights on yet. And have added some pods, I planned to add more pods this weekend. So I was just looking at the tank and found more than one aptasia on only the rocks I got from the person local to me. What should I do to eliminate it? I'm going to a really nice fish shop this weekend, it's almost a 3 hour drive so I couldn't get cycled rocks from them originally, but here we are. Should I just pull the rocks out with any aptasia on them and then get cycled rocks from the store I'm going to tomorrow and add those? I am kinda bummed cuz I wish he would have either told me if he had noticed aptasia in his tank before giving me the rocks because I wouldn't have just scrubbed them, knowing that beforehand. Thank you in advance for your help. Also not sure what the blue thing is behind the giant aptasia??
