I have brewed a handful of IPA's and my last three were NEIPA. First one was good. But second and third went bad due to oxidation and dumped the two after a week in the keg. The recipe called for hop additions at whirlpool, dry hop at two days into fermentation remove at 4 days and another addition at four days and remove at seven days. This is where I believe my problem is with O2 exposure and during xfer to keg. Looking at the fermzilla where the trub can be dumped and hops added via bottom or top and closed xfer to the keg. My worries are, if trub is dumped at day four will I dump the yeast to early? Is the fermzilla going to be my answer to my issues. Read good and bad posts about it. Or should I invest in a SS conical like a BrewBuilt Uni conical?
