Chemi pure during cycle?

[Hawkingcolorado]

Is just a skimmer the way to go during the cycle, or would chemi pure or something else help overall? I have a 12.5 gal AIO cube to start.- Thanks,Tim

I cant see the chemi pure doing anything for your cycle, specially if you have a skimmer running.
I'd leave it out for now
