Jut did a 30% water change yesterday and then tested my water and my amonia levels show nothing, but my nitrate is like at about 20, all other levels good. Thought maybe I tested wrong so did it again about 1/2 hour ago, amonia, ph and nitrite are good but nitrate is still around 20 which seems high to me. Should I do another water change?
