On this plant tank I've gotten away by doing only monthly water changes. So I'll definitely do as you suggested, and I'll also give the filter (Eheim 2026) a cleaning too, that has not been done for about 3-4 months maybe longer. The more I reread what I've added to the tank in the last little while, it sounds like it might just be a huge chemical soup.... Water changes first thing in the morning. Thanks again, hopefully it will be something this simple.
