So how often do we need to change the filter cartridge? I have it in since Dec 2, and the water still looks clear but not pristine. I had read that some people don't change it until the cartridge literally looks like it's falling apart. I have rinsed it only once and that was 2 weeks ago. I'm just going by the look of the water, which looks a bit hazy up at the quarter top of the tank.
Also, do we need to ever take apart the filter and clean it out?
