I am fairly new to the hobby (8 months to be exact) and have a couple questions for my new setup because i want everything to be perfect since im planning it to be an sps dominated tank.

1. Are refugiums beneficial to an sps tank?
2. Are mangroves effective nutrient removers? If so how many should i put in the refugium?
3. How much flow should i have in my display tank?
4. WHat kind of protein skimmer should i use for a tank this size?
5. What kind of chiller should i use and how many hp should it be?
6. Ive heard a lot of horror stories when it comes to calcium reactors? Are they really that complicated to use? Which kind do you recommend?
