read that the carbon cartridges on ugf's are inadequate and possibly dangerous(saturation issues). i have a ugf with a tetra whisper 20i air pump. i know i should switch to a powerhead but budgets tight. also have an aqua-tech 5-15 hob. should i take the carbon off of the ugf? i'm cycling with fish and doing 25-45% pwcs daily.
