If I'm using root tabs near my Amazon Sword because I'm told their a heavy root feeder plus I place root tabs near stem plants and places where Wisteria roots enter substrate. On top of all this I liquid dose Nilocg C weekly. My Nitrates run a little high but this should be expected with all the macro in my tank. My question is could I back off the liquid fert? I just emptied the bottle and I'm thinking root tabs in substrate dissolve and release nutrients into column anyways so why spend the extra money on liquid fert. Roots from Wisteria and other stem plant borrow into substrate.
