  • Patent number: 11608283
    Abstract: A method for improving the quality of pond water used in aquaculture applications by adding to the pond water active bacteria that are preferably germinated from spores on site using a nutrient-germinant composition and an incubation method for increased spore germination efficiency, in combination with a nitrification enhancement agent such as calcium carbonate or calcified seaweed, and an optional reaction surface area modifier such as calcified seaweed or plastic or metal particles or fragments. The nutrient-germinant composition comprises L-amino acids, D-glucose and/or D-fructose, a phosphate buffer, an industrial preservative, and may include bacteria spores (preferably of one or more Bacillus species) or they may be separately combined for germination. The incubation method comprises heating a nutrient germinant composition and bacteria spores, to a temperature range of 35° C. to 60° C.

  • Publication number: 20050145277
    Abstract: A feeder device for introducing treatment chemicals into a recirculating water stream from a swimming pool. The feeder device includes a housing having a top and bottom portions. A funnel-like hopper having sidewalls and an open bottom forms the inside of the top portion. A grid at least partially closes the open bottom of the hopper. The grid includes a top surface and a bottom surface. One or more chemicals such as chlorine are contained within the sidewalls of the hopper and supported by the top surface of the grid. A dissolving cup having a bottom surface and sidewalls is positioned within the bottom portion. The sidewalls include an opening or notch of a predetermined cross-sectional area formed therein. The bottom surface includes a center nozzle oriented vertically toward the bottom surface of the grid and an off-center nozzle adapted to direct the fluid horizontally in the dissolving cup.
