The LFS currently uses Fritz blue box as well which is what they recommended for me. I took a look around the forums for a bit and it seems fine enough and in general it seems like the salt you choose isn't as important as maintaining stability overall so ultimately went with Fritz since I know I can grab a box locally if needed.
Based on my levels historically, however, I'm not certain they keep things as high as I would like and I assume are dosing post-mix to make up for that. For example, my salinity has trended down over water change periods and I'd like to control that better.
Ultimately, though, I'd like to just get confident with mixing myself so that if/when I move to a larger tank I'll be better equipped (and be able to save money/trips to LFS). I'd say that's the number one reason I intend to switch TBH, otherwise I'm sure I could continue on with their water.
Not here to chase number dragons for sure, just want to be able to control the process start to finish so I have a more complete picture of what's going in my tank so I can ensure stability over everything
Quick edit, I do currently spot feed reef roids for the smaller mouths and usually give the euphyillia, nems, trumpet and candy cane some brine or even mysis when I feed that. Overall I'd say the coral are eating 3 or more times per week. They all typically have enthusiastic feeding responses, especially in the evening, and especially if I put in a few drops of polyp booster first.
