Newbie with questions/AquaTech filter and protein skimmer

[RandySC]

I am seeking the help of forum members again...I have a 55 gallon FOWLR tank with the following equipment:
1. T5 Dual 48” HO Aquarium Light Strip Cichlid marine Tropical Fish 108W 55g 2 Bulb
2. I have two (2) Koralia Wave pump power heads rated for 1050gph.
3. One (1) Aqueon 8,000k heater.
4. One (1) Aqua Tech 30-60 Filter.
5. One (1) Octopus Reef BH-100 Skimmer
6. Live sand and 45lbs of live rock.
My question is since I have live rock and sand do I need to run the Aqua Filter or can I get rid of it all together since I have the protein skimmer? Also, I am thinking of putting in a few mushrooms in the tank. Do I need a "refugium?" If so, I have been looking at a "AquaFuge External Hang on Refugium". Does anyone have any comments on it? Any comments or ideas would be greatly appreciated!!

It was my understanding that you needed filtration and a skimmer that they do significantly different things. If you have a refugium then I think you could do without the filter.
