I did some googling and found a few people saying they had the same sort of inconsistent/high results. I guess my question is, did I waste my money? Should I pick up a Salifert kit instead? Reviews on Marine Depot were positive, so I'm very frustrated about making a poor purchase/not doing enough research. I know $60 is chump change in this hobby, but still....
