Planning for a 180G tank, will be using a sump, so holes will be drilled into the bottom for the water going into the sump. the tank will be flush on the side walls, so no space for the return pipe outside of the tank, will it be ok to drill another hole on the other side for the Return pipe ?
Is there a table/chart where i can see how much water can flow down say a 1,2,3... inch pipe ?
