Skimmer ASM or Tunze or Hydor?

[Delphinus]

I ran a G3 on my cube (115g -ish). To be honest I wished I had gone with a bigger size. I was constantly battling nitrates. Now that I run a beckett on it, the nitrates have fallen down to zero and it's constantly pulling gunky skimmate out.

So, not knocking the ASM over the Tunze, from what I understand both are decent skimmers, but I would be worried the G2 may be undersized for your tank.

Never ran a Tunze so don't know how the ratings compare to advertised on those...
