ya reef crystals was definitely higher, I'm mixing up a 100 gallons at time so I do pour it relatively fast. Honestly with a mixing station TMP is awesome it dissolves so fast and clean I don't have to worry about cleaning my container. time is important to me and there's no risk of contamination if all i put in there is salt and RODI water. the price though, it hurts. if any other salt mixes cleanly and fast I'm willing to look into it.
