So I was just starting to get my Money Carlo carpet how I want it to be when a patch right on the middle started to turn yellow and melt. This has now spread throughout the entire carpet and I end up picking out large portions of the carpet from my surface skimmer. The tank has been slightly warmer due to the warm temperatures where I live. Could this be the cause of my melt? Tank is usually around 23C bit has recently been right about 26-27C. Here are a few pictures I took only 10 days apart. Has this happened to anyone else? I haven't changed anything with my dosing, photo period or CO2 injection. Somewhat frustrated at the moment
