The present disclosure is directed to an in-line soluble media delivery system. In at least one embodiment, the system may comprise a housing including an inlet port and an outlet port. The inlet port may accept a liquid flow (e.g., water). A soluble media (e.g., fertilizer, herbicide, pesticide, etc.) in the delivery system may be exposed to the liquid flow, and may dissolve in the liquid over time. At least one filter may allow the liquid flow, now comprising at least some of the gradually dissolving media, to exit the system without allowing the bulk of the soluble media to exit. In at least one embodiment the system may comprise two filters with different porosity.
