so i have a 240g tank and i'm running a 30g sump underneath with a flow rate of about 900 gph. When I convert this thing to salt I will need to increase the flow... my output and input can take it, but will the sump handle it if we loose power or will it overflow? When I loose power now it only adds an additional 7 gallons to the sump. When I increase the flow will it increases the amount if water in the sump when the power cuts off?
