Lexi B Posted December 12, 2021 Share Posted December 12, 2021 My tap water contains 20 ppm nitrate, and I want to optimize my nitrate consumption. Originally I wanted to add pothos to my aquariums, but since it's toxic to cats I just don't want to risk it. (My door is always closed, but it's not worth it to me) I'd like to avoid duckweed/water lettuce since it just takes over faster than I can manage. What would a good plant be that wouldn't be a danger to my terrestrial pets? Link to comment Share on other sites More sharing options...
