I have officially had it with Hanna. I just went to reorder alkalinity reagent and it's 17.99 on Saltwateraquarium.com. this is ridiculous and they will keep raising the prices because they know people need to buy it constantly. I'm done I'm switching to Salifert test kits. Hanna has officially lost my business. I realize it doesn't matter to them but I refuse to go support this disgusting behavior. Shame on places like BRS and Saltwateraquarium.com for not standing up to Hanna. They cave to this MAP crap.
