What filter media to use?

[RBZ80]

So i have an Aquaclear 110 on my 20 gallon nano reef and since start up i had one 11.74 oz bag of chemi pure elite, filter floss, and one bag of purigen. Both the purigen, and chemi pure have since been used up. I'm going to be redoing it and was wondering what you guys use (or recommend) for your HOB? I'm not looking to make it into a refugium, at least not any time soon.

I don't use a HOB filter but in my media basket I like floss, purigen and chemi pure elite pretty well. My water looks and tests beautifully with this

If what you have is working then why change it? Also, I'm not sure how much of an impact a refugium that small would actually make even in a 20 gallon.
