New sump design...........hit me with some input

[Myka]

How is an ATO going to work with two return chambers? Don't tell me you're manually topping off a 300-gallon tank...??

Why is a closed loop a PITA?

If it was me I would use one of those DC10000 pumps for a return with 2 or 4 nozzles, and then get a bigger pump for a closed loop. Those DC10000 pumps aren't near big enough imo. I would be looking at a Reeflo Hammerhead for each OM which would still only give you about 35x turnover.
