I am about to purchase a 75g rr tank it comes with some t5 lighting which i may upgrade in the future. I need to know a few things. First, is a 29 gallon large enough for a sump i plan on having a skimmer and a refugium in it. Second what size skimmer is needed and what size return pump. What size heater is needed. How much base rock (dried out live rock) and how much cured live rock will i need. anything ulse im missing like do i need a circulation pump. also i am interested in a nitrate reactor ive seen one on you tube that seems cool. as far as calcium i will probably dose but would there be any room for a reactor. Any advice helps ive not had a tank this large before, and my only reef tank was a nano 9 gallon that lived for 4 years before heater went crazy and fried the tank.
