Well if you have a "sludge" an a layer forming your problem might be else where an not the maxi.. Maybe some contaminant that's in the tank? When I say particles I mean I'm only left with like a dime size pile after mixing 700g's in a 5 gal bucket. And I'm sure this stuff have some sorta cheap fillers in it.
Well, I can assure you, there's no contaminants.. The flask was caustic cleaned and acid sanitized as it always is between brewing sessions.. I'll try a couple variations before making a decision.. In the meantime, I'm goin back to the jugs!
