Getting Back into Saltwater Reef Tanks

[Dnsburrell]

Hi all!!I have been messing around with fish tanks for about 15 years. I have had A couple of bad exsperiences with Saltwater Tanks. I am looking into setting up a 55gal or 75gal tank. I already have a Oceanic wet/dry setup with a Mag Drive model 7 pump.


I am looking for some advice on what I need as far as
Running a successful reef tank?


I want to know more about refugiums and how to set them up with a wet/dry sump.


Thanks
Any help is nice!!!'
