Port St. John sits between Cocoa and Titusville, but its water comes from Cocoa. Cocoa's water report lists Port St. John by name, and the numbers are the same: about 6.7 grains per gallon of hardness after lime softening at the plant, and chloramine to keep it safe in the pipes.
At that hardness, a modest softener sized to your household is plenty. If someone quotes a large, expensive system based on very high hardness, ask to see the test result and compare it with Cocoa's published average.
If you're on a private well instead, test it first. DOH-Brevard recommends bacteria and nitrate every year, and well water often needs iron or sulfur treatment before any softener.
