View Full Version : Cloudy water after water change and new carbon

02/03/2015, 04:21 PM
Did a 20g water change this morning and I also added a new bag of carbon to the sump. I usually change out the carbon every two months. Woke up today and the water seems a bit cloudy... Hmm. Everything looks great otherwise. Maybe I didn't rinse the bag enough? My skimmer cup was full of black crap..

Could this just be the new carbon?

I didn't rinse my carbon good enough once and my skimmer also turned black. I would just give it some time.

+1, if it's black crap it's carbon dust. It will clear up. If there wasn't black crap in your skimer cup I'd say it was some sort of precipitation from the new water not being properly mixed/desolved. I had this problem one time before I knew you have to add salt to water, not water to salt.

First off you change your carbon every 2 mo?? At least every 2 weeks..
