Need help before starting up

[iconz84]

Hi reefers,
i am new to this hobby.. I wish to start a reef tank.. I have read some books and also view videos on youtube regarding setting up reef aquarium. I had also followed some threads on advice of what might go wrong with a reef tank..

Here i seek some one to explain regarding the requirement of calcium reactor & doser.. And most probably any other reactor i might need.. As from what i know reef needs abt 380-440ppm of calcium to thrive on.. Please explain.. Thanks..

My build:
3*1.5*2 tank
2*1.5*1.5 sump
Hilea chiller
Protein skimmer - tunze
Return pump
3ft t5 light (think its mh) for tank
diy pvc overflow

Just some additional info, i do have sand substrate and also live rock

I don't know very much about reactors but most people maintain a good level of calcium with PWC I think

I'm go'n to get a phosphate reactor myself to help keep phsphates as close to zero as possible.
