I have trouble keeping nutrient >0 and resort to dosing . I have a small tunze 9004 dc skimmer . Not pulling a lot out but I kept it running 24/7 for oxidation. 
I am considering just pulling the plug. Could use the limited space on my aio tank. I am not concern about nutrients, but what about oxidation?
