Hi, my macro mix becomes unstable with some white algae substance and stuff falling out of solution after about 1 week or less. I have another channel on my doser and I'm wondering if I remove one compound from the mix and put it in another dosing container, this would increase the shelf life. I suspect Potassium Nitrate would be the candidate. Currently it's (85g) KNO3 , (60g) K2SO4 , (10g) KH2PO4 , (30g) MgSO4 into 1L distilled (which is split across this tank and several others.) See parameters below, also journal. TLDR: 1) Which compound to remove? 2) Also, can I use ascorbic or p sorbate in my macros mix for shelf life? Thanks for your time and consideration.
