I didn't know I just needed this one simple powder for a healthy shrimp and healthy Aquarium. Mind you I have to use a tip of a toothpick which is enough for a small three to five gallon aquariums which I own. I do not recommend using the whole scoop even with a large aquarium like a 10 or 20 as it can cause danger to the inhabitants. Overall I'm completely satisfied and the shrimp love it.
Thank you for another great purchase.
Works well !
Got it along with my shrimp and it works great.
Amazing food that all my shrimp love! Highly recommend.
