So I'm switching to fritz blue box from tropic marin it should arrive next week sometime. I have a question for anybody using the fritz, if I mix to 1.025 what should I expect the actual alk levels to be? Fritz says it mixes at an alk of 8-9 for 1.0264 on there website. I mix to 1.025 so I'm expecting a bit lower alk anybody have any real world experience?
