Abstract

A time-release composition and method of making and using the time-release composition. The time-release composition may include an active ingredient that is useful in deterring unwanted growth, such as bacterial and fungal growth, in high-flow water environments. The composition can include several active ingredients to provide a multiple use tablet. The multi-use tablet can be used to dispense any combination of active ingredients that act as clarifiers, minerals, medications, buffers, chemical dosing, and/or other maintenance components, such as growth deterrents and water filtration augmentation and any combination thereof.

First claim

What is claimed is:

1. A tablet holder for dispensing a chemical formulation comprising:
a body portion, wherein the body portion comprises a first side, a second side, and an solid edge from between 90 degrees and 270 degrees along the first side and the second side, at least one of the first side or second side comprises a plurality of apertures, the plurality of apertures sized to control the rate of dispersal of the chemical formulation in a high flow environment and wherein the first side and second side are substantially similar in size and comprise a fixed distance between the first side and the second side in a use and non-use configuration,
wherein the first and second sides are connected via the edge, whereby forming an internal cavity, wherein the edge comprises an opening, wherein the opening of the edge is in communication with and permitting access to the internal cavity, and wherein the internal cavity is sized to allow for a metered dose of the chemical formulation to be placed therein.

2. The tablet holder claim 1 , wherein the first side and second side each comprise at least 6 apertures.

3. The tablet holder of claim 1 , wherein each aperture is sized between 0.25 mm to 1.75 mm.
