I feed an assortment of Mysis, brine, rods foods, fresh shrimp, krill, nori, anything really, I try and mix it up everyday. I do only feed once a day due to work. I read all these threads and hear people say they feed 2-4 times a day and think, do these people not have jobs!? I'm gone before the lights come on and return to just a few hours left each night.
And I agree about the mag, the sailfert kit I have is now pretty old and I question if I trust it.
It's funny, for months I've thought my skimmer hasn't been doing a great job. Guess it's keeping up ey.
