i added some red slime remover about 2 weeks ago and immediately my xenia stopped pumping. I figured it would resume after a water change or two but, nope. It also appears more tan in color than the bright white it was. What do you guys think.

I did,,2 ,,20 gal the 1st week after doing the chemi clean ,and another 20 a week later ,marrone said:After using Chemi-Clean your surpose to do a large water change. 8.1-8.3 is fine but some Xenia will only start to pump at 8.3 and above.
