Since I put the wall in. I used all BRS dry/base rock, Nothing was alive including the wall at the point of the last pics... well other then the few pieces of coral and some live stock. this was to completely eliminate any possible aptasia infestation! I did however Get one or two in the tank. This took me a bit to figure out, could it be, spontaneous generation? NOPE! Haha it was from the macro algae I bought from my LFS... Didn't think of that! Its all good though, a bit of Red Sea Aptasia X and POOF, Gone!
