Ok, so I just started to set up my 29 gallon reef tank, so far its just the tank and live sand and some crushed coral, a store here will sell me the water premixed for 1$ a gallon to fill up on, so i was going to get about 20 lbs of live rock and add it the same time as the water ect. how hard will it be to get it going? ive seen how some people say to set it up and it sounds ALOT more complicated than they said at the store, at the store they said add the sand and live rock with the saltwater, keeping the salinty at about 1.024 -1.026 and after about 5 days add in a damsel to get the cycle going (the live rock is cured and have undergone the cycle already) and about 4 days after that i can add the fish i want (2 clowns, and a firefish) and thats about it for now. how hard will this be to set up? or were they pretty much right on what to do
