something in my tank just doesn't look "right". after the power outage it looks like something in the tank is different. you know the "look" you have when you know everything is "right", well that "look" is gone. seems like the color of everything is wrong. could this still be stress ?? or should i be looking for something ?? i know softies let off toxins when stressed but i did a 20gal water change 2 days ago and i added some new carbon tonight. guess we'll see how things look in a day or two. any suggestions while i am waiting on the carbon to do its job ??
