I have fast growing pothos and duckweed cleaning my aquarium water. Should I topoff or remineralize?
So I have pothos and duckweed growing really fast and draining the water out of my aquarium. Do plants absorb pure water and ammonia only? Or does it absorb water, ammonia, and minerals too? Should I add distilled water to top off my aquarium or remineralized water instead to top off the aquarium?
