With or Without Skimmer

[Molino]

I thought I'd run this past you guys before I change anything on my system. I have a 55 gal SW tank. Right now I've got 6 fish in it along with a number of corals (zoos, xenia, mushrooms, Rics, etc) some hermits and a bunch of snails. It's a new tank and has been up and running since about March.

It is in my bedroom, so I had initially hoped it would be as quiet as possible. That is not the case. I have a Remora Pro skimmer hanging on the back which due to the way it sprays water in, is not at all quiet. I have created a box which somewhat surrounds it, but it is still not very quiet.

My question is this. Can I get away with removing the skimmer altogether if I increase the water changes? to say 20 gallons (approx 40%) per week?

As an FYI I also have a small DIY refugium hanging on the back made from a AquaClear filter with several types of macro algea.

Thanks for any help.

edit: I should also note that due to the design of the tank stand there's not really any room under the tank for a sump.
