Pond Boss Forums INTRO Questions & Observations Will my fish make it through winter???

I think if it doesn't get cold enough to ice over (or even if it ices over a little, i.e. cold enough for thin ice), the CC and FHM should be OK. Northern BG would be OK too; we'll have to have a Southern input on the CNBG. I half remember something about CNBG and ice/water temps, but not enough to try and voice it out loud.
