So I decided to skip last week's water change to see how my aquarium would handle it. I tested the water and I noticed that the nitrates are low. Is that good? 10 gallon planted with: bacopa c. Amazon swords Anubias nana 3 male platies 0 ppm ammonia 0 ppm nitrite ~10 ppm nitrate Oh and I had DIY CO2 running until from Thursday to Saturday. It's a low tech tank so I only use Flourish root tabs.
