I never secondary my beers unless i absolutely just need the fermenter space. Throw the cacao nibs and PB2 powdered peanut butter into the primary, it'll be fine.
I run a 3 vessel electric RIMS system on a 240V 30a circuit. The RIMS tube is a 2000W 120V element and the HLT and BK are both 5500W 240V each. BUT the HLT and the BK are on a 3way switch so only 1 240V element can be on at any one time.
It will settle with some time. Or if you have the capability to cold crash it then that would speed up the process of dropping everything out of solution.
Seems a little silly to me to have your system tied up in one beer until its completely consumed. Yes you can push it into another keg but then you are only utilizing half of the system that you just paid $1800+ for.
As Mirilis stated, the +/- 2 degrees is a big deal for fermentation.
Ive been...
I have the 7 gallon SS Brewtech Brewmaster Edition with the casters. I built a 9 gallon glycol chiller system for temp control and it works really well so far in the warm garage. Everything about this conical i like and i dont have any exp with any other of the conicals. Was worth the price to me.
Wonder if you are oxidizing your beer between primary/secondary transfers or during bottling when added priming sugar. I remember i also use to have the "certain" taste that was in ALL my beers. Things ive changed since then are i ALWAYS flush everything with CO2 when moving any amount of beer...
