Topping off water in tanks.
Hey all, quick question i had,
When topping off due to evaporation, i understand that the minerals remain behind from the evaporated water, would just topping off the evaporated water with RO or distilled water suffice? Then after a while, do a larger water change, to like compensate for too much minerals accumulated/too little minerals??? Or am i misunderstanding this whole water change business. Can someone please explain it to me?
Cheers
EDIT: I understand that large water changes are not very necessary, but i mean just in regards to topping off due to evaporation.
