Hi guys! I'm trying to figure out if our filter is in the right position. The setup is chem tank that has an overflow which take the excess chem to a sump tank, after the sump tank there is a pump going to the filtration system and back to the chem tank. there's also a pipe from the chem tank that is connected to the pump. The filter is 1 micron. So our filter is placed before the chem tank and after the pump. The chem process happening in the chem tank is producing contamination which we know know what exactly is so we cant eliminate it. We are currently skimming the chem and sump tank manually to reduce the contamination but we cant do it continuously. I'm thinking, maybe we should relocate the filter to be before the pump, or maybe after the overflow. Is there any difference? what would be a better setup for this circulation?
