The charcoal filter is purely optional and not vital to the wellbeing of your fish and plants at all. I often use filters like that when my growbed volume is not sufficient for the water volume in my system ie. if I don’t have enough growbeds. There will always be a gradual build-up of undesirables in your system over extended periods of time. That is why I do partial water changes every couple of months.

I have question, what if your system do not have that active charcoal filter (including other stuff) then will your system work as it is now? What I mean is that I want to try a small aquaponic system but I didn’t build any filter, will my system survive (fish and plants) without a filter?

How important is charcoal filter (including other stuff) filter? Because as you said that active charcoal has a very large surface area, thus it can filter out many nasty things.

After reading your article, I am under impression that after some months, the water in my system will be loaded with unwanted things and my fish and plants can suffer or die out.

Please reply, thank you.
