A couple days ago I cut my toastood to make it smaller. The 8 smaller pieces that were cut from it are held down with toothpicks. Before I cut it, I measured my NO2 and it was zero. Today it is about 0.3. Apart from a raised NO2 my skimmer also stopped skimming.
Can someone tell me if the toastood is releasing something into the water that is causing these problem?
