I have a Reeflo Blowhole BH100 which is a pressure rated pump that has an adjustable watt draw option as well and I do like that option. These Waveline's kinda remind me of it, but I like the options for controlability better on the Waves. The only thing that I would think hard about is rating 22ft rated pressure height. While it's a bit for most, for your application the flow is quickly going to drop by the time it goes through those 4 filters, UV, Chiller and then up to the tank. While lowering the watt draw is a very nice option that will have an impact on pressure performance so I don't believe you will even use that.
If I was in your position I would use a higher pressure rated pump for the filtration and a flow bias pump for circulation. IMO you need to look at 30ft + head pumps minimum to drive the filtration side.
