I stick by my original statement of it seems like everything added is ok. Of course keeping it simple is always better, but I don't see anything wrong with what is added with the exception of directly adding N03 and P04. The OP is correct with the adding of AFR and that is such a minimal amount that I don't see that as an issue. Microbacter clean and 7 also don't break anything on a weekly cadence and you can watch the BTS tv episodes on it for going through the ugly phase on new tanks, so seriously shouldn't be an issue. Chaeto grow is questionable, but I understand that since you are doing a refugium that you think it is necessary, but I'd avoid it until the Chaeto starts to suffer. AFR has iron, and that is something that if it is too high in your tank can be harmful.
