A chemical release system. Implementations may utilize implementations of a first cartridge that include a body coupled with a cartridge head at a first end and coupled with an end plug at a second end where the cartridge head includes a through hole configured to engage with an annular flange in a main head. The body may have an internal cross section. The first cartridge may also include a flow restrictor plate disposed within the body between the first end and the second end where the flow restrictor plate is oriented substantially parallel to the cartridge head within the body, includes only one opening therethrough, and substantially conforms with the internal cross section of the body. The body may include one or more through holes in a side of the body located between the flow restrictor plate and the cartridge head.
