Here is a video all about our new packaging. This packaging can be used various ways. You can use it to spot feed without any water coming back into the package, which could cause dilution. You can also use it to simply open and pour in. For those of you who are interested in feeding a more natural, continuous way, you can set up the bag to hang over your aquarium and slowly drip in! Any way you choose, your aquarium will appreciate the nutrition!
