I just did a 100% water change on Thursday. Now the water looks green, foggy and dirty. I know it's not because of the amount of water I replaced because I do a 100% change every 2 weeks. I have to because my fluval 4plus just isn't cutting it anymore. I'm looking into canister filters but it's a ways away yet. I did change the media but I've done it before and the water goes a little foggy for a day or so but never green or dirty. I just don't know what happened. 2 days after a complete cleaning, and the water looks like it's been sitting there for 2 weeks.
Input anyone?
