l-dex is armidex.......aqua-dex is similiar to nolv.....completely different. The cloudiness is the powder falling out of solution, which will happen over time.......use heat. Either micro wave for 4-5 sec and shake, or I would use low heat in a pan with 1in of water in it on a stove....5-10 min,it will be good shake the hell out of it ever 2-3 minutes.
