Hey? Hi? wassup? I don’t really know how to start a thread, this is my first one. Anyway, I have a 45 gal planted tank with discus, angel fish, and some guppies. I guess you can call it a nano-tank, but I am offended. Soo it’s about 6 months old. The levels are 0 nitrite, 7.0 ph, and the nitrate levels are at least 70 ppm. I have no idea what cause the nitrate levels to spike. I have had perfect water for a long time, and I do 30% biweekly water changes. I honestly know it’s from over feeding, but I SWEAR TO GOD it say you should feed baby discus at least 12 times a day. Of course I don’t do that but I do feed them twice a day, an mix of blood worms and pellets. I don’t really know what to do. I changed the carbon on my filter and I been doing water changes every two days. I read some horror stores about nitrate levels being to high for to long and killing the fish. So that’s why I’m here— for advise. Let me know if you got any ideas.
