Plants

[stroppy]

this has been puzzling me for ages so ive just got to ask ...if your bio turns amonnia to nitrite then nitrates and then your plants get rid of the nitrates or at least some of them, how do ponds do that if they dont have plants ?

water changes. that how most aquariums do it as well. no plant in my 75gal tank so i have to do water changes to get them down.
