I never learned about macro vs micro, I will start with npk from seachem and see. My tap is very hard, and I just read the ingredients for root tab, canít see much npk there either. I am guessing slowing down on feeding due to less guppy is starting to show lack of macros. It was never really stellar to begin with.
I am about to start a new tank with organic potting soil, glad I am a bit more armed with more info now. Thanks
