help choose a calcium reactor for my 180 gallon

[matts125]

so my redsea max s 650 has a total water volume of just shy of 180 gallons.. I plan to have a fully stocked mixed reef with clams and SPS as well as LPS this tank will have a moderate load..

This calcium reactor has really caught my eye an I want some feedback on it.
its the Korallin 1502

anyways it claims to be rated for 400 gallons how will it do on a moderately stocked 180?
other suggestions?

Aquamaxx S1 S2 or S3 a S2 should work great for you.
