zpayne10 Posted March 7 Share Posted March 7 Do most people add fertilizer after a water change? I'm specifically curious for those with new tanks, if you're doing water changes a few times a week to try and prevent excess nutrients, do you add a few pumps of fertilizer afterwards? The 'right' answer is probably to test you nitrates after each water change and determine if you're within a desired range or not, but maybe there is a faster/better answer.
