probably not the right place but here goes.
i`ve aquired a swimming pool sand filter which i want to convert from sand to kaldness k1 so it becomes a fluidised bed filter the thing is i want to feed from my overflow and then return it to my sump will the gravity work ok like this please?probably sounds stupid but got the filter for free so if doesn`t work then fine.
just a massive amount of biological filtration for very little cost.
cheers
