I'm not sure if it's that massive of an airstone, but he pushes a lot of air through it. You really need a large air pump over a large airstone in my opinion. He even addressed that in one of his videos.
From what i remember he is using a 3" air stone with a 110 lpm air pump. Im not sure where he got it but i think they wouldnt be that hard to get. I hope you find what your looking for, have a nice day.
Hi
I'm after the air tubes he (Uarujoey) uses to fluidised the k1 media but I can't find them at all, all I could find is the long thin air stones which look like air tubing but does anyone know if they will fluidise the media the same way ?
Thanks
