I realized after doing a lot of reading here that I was not confident in the temperature of my tank. I ordered a Thermapen and it got here last night. Mercury thermometer reading: 78. Thermapen reading: 86! I have been wondering why my plants were giving off distress vibes (besides my terrible noobness) and I think that may be part of the problem.
So, tank got bumped down and this morning got a small bump down again. Hopefully that is the last adjustment to get to 78-79.
Starting this tank as a “practice” tank before scaping the office tank may be the smartest thing I have done. I have made a bunch of errors that I can learn from and not repeat (big assumption).
