Feeding Directions

Shake thoroughly before use to evenly distribute the contents.

YelloSno can be broadcast throughout the aquarium or used for more focused feeding of suitable corals and invertebrates.

For broadcast feeding, add the appropriate amount to an area of good water movement to distribute food throughout the system.

Begin conservatively and adjust feeding based on livestock density, feeding response and aquarium nutrient levels. Avoid excessive feeding to help maintain water quality.

Follow the current Hydrospace dosing recommendations printed on the product packaging for specific feeding amounts and frequency.

Storage

Refrigerate after receipt and between uses.

Keep the container tightly closed and shake thoroughly before each feeding.

YelloSno does not require refrigerated shipping, but proper storage after delivery is important for maintaining product quality.
