Therefore, IMO, it's not just the overfeeding of the aros right? It should be more of whether the BB in the filter media is efficient enuff to breakdown the waste matters?

Moreover, the excessive amount of lights can also be a cause of the green water isn't it? Lastly, to remove the green water,would the passing of the water through a UVC be the best way (would this kill off the BB in the media too) or thru multiple WC? If through multiple WC, then how to change less so that parameter is not affected so drastically to cause stress while ridding the 6ft tank of the green water leh?

Just for discussion
