I have a shelf of additives and don't use *any of them. Lucas Formula with 1/3 add-backs. My forty gallon res has not been changed in six weeks and the roots are exploding and white as snow and the pH is easy to manage.
*A touch of Epsom Salt (Magnesium Sulfate) seems to benefit the Lucas Method after a few weeks of no res change.
