Would a reef flow (sequence) hammerhead pump be to much for a heavily stocked 220 gallon CA/SA cichlid tank?
Overkill - Too much filtration?

Too much unless you necked down the return. You'll turn your tank into a whirlpool. Here's what the flow looks like in our 300 gallon tank with return necked down to 1"

My oscars went body surfing in the strong current.

You could use the extra flow to run a uv sterilizer or other peripherals....

The question of "too much filtration" really depends what the pump is pumping water through. The head height and plumbing diameter will help determine it, but going by the video pacu_mom posted it certainly looks like it would be too much flow (which is different to too much filtration).
It'd be going though a 40 gallon sump. The back up to the tank (5-6') through a tank long spray bar.
At 0 head, the flow rate for the Hammerhead pump is 5800 gph. Even at 8' head, the flow rate would be in the 4000 gph range. 4,000 or even 3,000 gallons of water an hour through a 40 gallon sump is crazy. How are you going to get that much water flowing into your sump? I have run 800 - 1500 gph pumps for my wet/dry filter return. I run my Hammerhead pump on a closed loop mechanical system. If I were to plumb the Hammerhead pump to my wet/dry filter, the wet/dry filter would be pumped dry in less than a minute. (It's just a 28 gallon sump, but even if it was 12 gallons larger, it would still be quickly pumped dry.)There is no way the flow rate from my overflow box could match the flow rate of my Hammerhead pump. I love Reeflo pumps, and have never considered using any other brand, so I'm not trying to discourage you from using Reeflo pumps. In fact, I will be using a Barracuda Gold pump to return water from the sump on my big system which has yet to be set up. My sump tank is large, so I won't have to worry about pumping it dry.
You should calculate the reasonable maximum flow rate through your sump and select a pump that would have that flow rate at 6' head, or consider using the Hammerhead in a closed looped system.
How about the Reeflo Dart/Snapper hybrid? It comes as a 2500gph, but includes an extra impeller to change it to a 4000gph pump.
Exactly. You dont want to blow water through the sump too fast or there will be less contact time for the bacteria to do there job. Figure out how much flow you need through the sump. Add any other equipment you need to run. Then get the rest of your flow for the tank in power heads or a closed loop system.
