they call me fish geek ;p
I did a 45% water change yesterday bc my nitrates were still testing at 20ppm. I tested my water today and they read at 10ppm.. shouldn't they be at zero after such a large water change? I have four small fish, I don't overfeed, I have a protein skimmer. I keep up with my water changes. Nothing has died.. idk what's going on. I'm starting to think its my test kit giving me false readings. My nitrates should be at zero. I did two 25% water changes last week. I did a 45% water change yesterday. There is no way the nitrates.can creep up that fast is there? It's a 29g reef tank with lots of inverts. The only illness in my tank is my jawfish with ich. He is struggling to pull through but he seems to be recovering slowly. I'm stumped....my lfs says my nitrates are zero but they don't shake the bottles before they put the drops in so I don't think they are accurate. What do you guys think? Am I wasting my time and salt by doing all these water changes? What could be causing nitrate levels? I do use tap water but I tested my plain tap water and it tested at zero.
