No, you don't have to make sure your flow is right.... you'd have to make sure your flow is perfect
, or you're going to overflow one or the other. In other words, VERY bad idea. The best set-up is an overflow in the tank and a return pump from the 'fuge. That way the only water coming out of the tank is what's being supplied to it..... if the pump dies, the water coming back to the 'fuge stops as well. If you have two pumps, and one dies..... well, I have a good mental image of that
Problem I have with a siphon is that if you have a power outage, your pump stops working, but the siphon will continue until it gets low enough to break said siphon. Then the power comes back on, water starts going back into the tank, but you no longer have a siphon returning to the 'fuge..... again, another entertaining mental image.
