According to my math for the water changes I have done and Cuprisorb, the copper should be completely gone from my tank by now. However my Hanna checker is still reading 0.04 over a couple different tests.
Could it be leeching from something? No rock or sand, just pvc pipes. Could it maybe be from the filter media?
According to the Hanna's instructions, it has an accuracy of +/- 0.05. Seems like a pretty large error bar for something that requires a pretty specific dosage. Anyways, if I am understanding that correctly, it is possible I have zero copper, but the hanna is still registering?
I'm inclined to believe it's gone because ever since my last water change, copepods have covered every square inch of glass.
What do you think? Suggestions?
