So im starting school and getting into some sps. im worried that when i add a decent amount of sps and change my wc schedule from once a week to once every 2 weeks my magnesium will deplete faster then normal. as of right now i only use kalk in my ato and my wc to keep my parameters in check. so what would be a better buy for me; premixed magnesium or powdered magnesium for automated doseing for my 90g? also if you could tell me what brands you use or recommend that would be great. thank you in advance.
