CPR Bak-Pak vs Tunze Nano DOC

Which skimmer between the CPR Bak-Pak vs Tunze Nano DOC would you prefer for a 20 gallon SPS dominated?
Thanks

I thought you already had a Tunze.

I have a CPR Bak-Pak on both of my 20's and they do fine. I have not used the Tunze.

I had a tunze but sold it when I got outta the hobby. I've never owned a BakPak. Just wondering others views

I liked my tunze. But been looking at bakpaks

Go with the cheaper bakpak and maybe mod it some with an air stone. Since your just running a 20 gallon, but if you have the funds i guess get the tunze.
