Well, I thought it was going down, maybe it did a little bit, but hasn't changed much lately. I decided to go a step further, I slowly increased the temp to 84 in my temp, which is max on my thermometer, then gave the heater a slight touch more so it's around 86 I'm hoping.Now to leave it for the next week or 2 to see if it helps. I've also placed my powerhead back in with the air intake attached to add air to the output. Hope things get better soon.....
