Need to I.D. some algae in a new cycling tank

Tank has been cycling for a few weeks and I need to check for any problems before adding fish. Help would be appreciated!

 

Pic#1 coralline algae + possible Green Turf Algae
Pic #2 Cladophoropsis or Caulerpa Racemosa (if little grapes appear)
Pic 3 Feather Caulerpa
Pic#5 looks like a coral - possibly a moon coral - or a type of sponge if it's soft

 

^^ what he said lol, agree that the last one looks to be some closed polyps to me.

 

I see a lot of aiptasia in that second pic. That needs to be dealt with and the easiest way to do it, since there are no fish is pull the rock and bleach the crap out of it in fresh water, rinse well, let the rock dry, put it back into the tank and begin cycle again. If not, you are going to have a HUGE battle on your hands.

 

what type of tank are you thinking of running, fish only corals??? I agree with all the above, but I would remove the caluepra also! It is sometimes good in a sump/refuge (though i dont use caluepra) but can cause other issues!

Looks like some of the rock is mature, so you shouldnt have a massive cycle so the last coral might make it! Freebie.......bonus
