I've been keeping freshwater for almost 8 years and now I'm getting into saltwater. I'm starting off with a 55. I would like to keep soft coral with some fish like a snowflake eel and some others I'm not sure of yet. My question is, I have a skimmer that world run on a 125 and two 70g hang-off the back filter. I also have 30 lbs of live rock and will be getting more. Do I really need the 2 h.o.t.b filters, it's it too much to were its unnecessary? Will add pics when water clears up, thank you!
