i m keeping some normal LPS for my tank n i dun use a CR... my advise is juz do a simple set up for ur tank first...eg, get the basic stuff (chiller, skimmer, lightings,FR) for CA,MG, KH u can use manual dosing first... play ard with ur system after cycling then u will have a better understanding of how to maintain ur tank. maybe u can maintain ur tank with manual dosing so u can save the money of the CR. denitrator u will not need it so soon or u may not even need to use it if u r not overstocking ur tank.
my final advise is reefing need lots of patient. whatever u do, dun rush.
