Sulfur reactor cloudy discharge


New member
Ive been running a sulfur reactor for about a year and a half(approx) and about every few months the reactor inside turns milky and turns my tank cloudy. The numbers are all ok, nothing in the specs seem to change and after a few days the cloudiness disappears. Can anyone explain whats going on?


There is no substitute.
The denitrator is probably pushing out dead bacteria that has decayed.
I use a sulfur denitrator, and every year or so I take it apart, clean the media, meaning rinse it out with some water from a water change, wash out the reactor itself, reassemble, and place it back in service.

Clean your reactor at regular intervals, and you will avoid issues like you describe.
