Every calcium reactor will work. But every reactor has its limit. If your animals need low calcium and alkalinity every reactor will do the job. But if you need more - e.g. your animals are growing - you must raise the power. If a reactor is at its limit and you raise the inlet flow you will have more power but more free CO2 in your aquarium, too. This too much CO2 will cause green algae growth. And I am sure your hard corals do not like it. - In the last 10 years we have seen many hard corals tanks with big problems to maintain Ca and alkalinity. After installing the AquaCare Turbo reactor the problems were gone. - But be careful: start with only a few hours daily operation time. The biggest mistake is to run the reactors 24 hours per day. Within one or two days you have so much Ca and alkalinity that calcium carbonate will precipitate and your whole water chemistry is upside down.

it is always nice to hear from the actual builder My 618 is at its peak right now , need something new, MORE OVERTIME @ WORK for one of these

Well I have a model 3 and a model 4. If everything is hooked together in your system a model three should hold you nicely. I have a model 3 on a 445 gallon system highly loaded with SPS and I run it for 7 hours per day. They say a model 3 is good for up to 650 gallons but that is understated in my opinion, it is likely considerably more.
