I'm going to start. I read some good articles on it and watched some YouTube videos. Once you do the initial mixing you shouldn't mix any more. No powerhead. The stuff that settles at the bottom is impurities and "heavy" lime water. This stuff can jack up numbers quick. The recommend having your line elevated above this murky water at the bottom. I'd invest in the 12 buck aqua lifter and airline tubing so you can have the hose right above the effluent.
