So I am set on the DC pumps and just ordered the speedwave 5000 pump from PA, but it's on back order for a couple of weeks and I wanted to get started on my build right away. So I'm looking now at the Waveline 4000. The price is about the same but this Waveline can be controlled by my RKE but it's about 300 gph less than the speedwave 5000. Would this still be an adequate return pump for a 25 cube with about 4-5 feet of head between tank and sump and a manifold off the return for media reactors, or should I just hold out for the speedwave 5000 for the extra flow?
