Water changes actually can't take the place of a resign like Purigen. Not on the polishing front and not even when it comes to removing tannins from water.
Stick to what you're doing, OP, as you have the right idea and won't regret it. Crystal clear water.
i'd like to clarify in red. its IMPOSSIBLE to overdo water changes
unless shrimp are involved
no fish, nor plant will ever show any signs of complaint about a good water change
