Hi there.
I have a 65 litres aquarium. At the beginning I had 3 male guppies and making weekly 20% water change's I was keeping the nitrate levels between 10 and 20 ppm. Now that my stock went up to 8 guppies, the nitrate levels are above 40 ppm. I don't want to do 50% water change's and my fish looks happy. What do you guys think about my dilemma? What's the absolute maximum ppm value, at which is better to do big water change's in order to reduce it?
Any comments on this subject are welcomed.
