Hey, its working great, I can take a picture of it vortexing next time I have it going if youd like.
The hose goes down 2/3rds of the way. You can play around with how far down it goes and use what works best for you.
Also, make sure you get a large pump, bigger the better. That is if you want it to vortex properly. The more dissolved oxygen the better right?
The carboy I'm using is actually the same size as a 5 gallon bucket, & the reason for using it is so that the induction-like bottom allows it to spin easier & I would think less dead spots for sediment to build up.
Also with only 1 pipe feeding the jug, it is very easy to clean.
Hope this helps.
