OK - so ive bought my tank ~50 gallons, put salted RO water in and coral sand. Left it for 2 weeks and then went and bought 10kgs (22lb) of live rock. Apparently the rock was checked beforehand but I found a crab hidden away which seems to be doing fine - although a bit wary and doesnt come out much in the daytime. The rock has been in for about a week maybe 2 now and i'm starting to see things growing. I've been checking Salinity/Ph/Kh/NO3/NO2 daily and everything seems to be perfect, although my kit probably isnt the most accurate. I've got a couple of pictures just wondered if anyone knew what this is growing on the rock (theres some white mould looking stuff and also bottom right an orange thing covered with white mould :

Also every morning when I check the tank I seem to be seeing more of what looks like animal waste of some description -anyone got any idea? (its the long brown thing theres quite a few of them now but all I have is one crab over the other side of the tank) :

Any help would be appreciated, on the pics mainly but also on how long to leave it before adding livestock - if my readings from my test kits are to be beleived the tank is ready now?? (Its been about a month).
Cheers in advance guys
