What is claimed is: 1. A device for controlling microbial growth in potable water systems, said device comprising: a flow-through housing having a housing wall structure, a housing volume surrounded by the housing wall structure, and one or more openings within the housing wall structure; and fluid treatment media occupying at least a portion of the housing volume within the flow-through housing, said fluid treatment media comprising a physical mixture of: a first set of particles or beads comprising an anti-microbial component coating on a support material with the anti-microbial component coating comprising one or more coating layers on said support material, said anti-microbial component comprising silver and said support material comprising alumina; and a second set of particles or beads comprising a scale inhibitor comprising glassy polyphosphate particles; wherein the support material has a particle size that prevents the support material from escaping the one or more openings within the housing wall structure. 2. A device for controlling microbial growth in potable water systems, said device comprising: a flow-through housing having a housing wall structure, a housing volume surrounded by the housing wall structure, and one or more openings within the housing wall structure; wherein the housing wall structure of the flow-through housing comprises: an upper half, a lower half connected to the upper half, and a filling cap connected to the upper half or the lower half; said one or more openings being positioned within the upper half, the lower half, or both; and fluid treatment media occupying at least a portion of the housing volume within the flow-through housing, said fluid treatment media comprising (1) an anti-microbial component coating comprising silver on (2) a support material comprising alumina with the anti-microbial component coating comprising one or more coating layers on said support material, and (3) a scale inhibitor comprising glassy polyphosphate particles; wherein the support material has a particle size that prevents the support material from escaping the one or more openings within the housing wall structure. 3. A device for controlling microbial growth in potable water systems, said device consisting essentially of: a flow-through housing having a housing wall structure, a housing volume surrounded by the housing wall structure, and one or more openings within the housing wall structure; and fluid treatment media occupying at least a portion of the housing volume within the flow-through housing, said fluid water treatment media consisting essentially of: an anti-microbial component comprising silver on a support material comprising alumina; and a scale inhibitor comprising glassy polyphosphate particles; wherein the support material has a particle size that prevents the support material from escaping the one or more openings within the housing wall structure. 4. The device of claim 2, wherein the fluid treatment media comprises a physical mixture of (i) a first set of particles or beads comprising said support material coated with said anti-microbial component coating, and (ii) a second set of particles or beads comprising said scale inhibitor. 5. The device of claim 1, wherein said device consists essentially of said flow-through housing, and said fluid water treatment media with said fluid water treatment media consisting essentially of said anti-microbial component, said support material, and said scale inhibitor. 6. The device of claim 1, wherein said glassy polyphosphate particles have a chemical composition comprising (Na10Ca2P11O35)xSiO2. 7. The device of claim 2, wherein (I) said device consists essentially of (i) said flow-through housing and (ii) said fluid treatment media, (II) said flow-through housing consists essentially of said upper half, said lower half, and said filling cap, which together form a spherical housing wall structure, and (III) said fluid treatment media consists essentially of (1) said anti-microbial component, (2) said support material, and (3) said scale inhibitor. 8. The device of claim 2, wherein said glassy polyphosphate particles have a chemical composition comprising (Na10Ca2P11O35)xSiO2. 9. The device of claim 3, wherein said glassy polyphosphate particles have a chemical composition comprising (Na10Ca2P11O35)xSiO2.
