PE Mysis heads up

They are gut-loaded so you are not washing anything away besides pollutants to your tank.

My skimmer level plummets for hours and the skimmer section is all foamy and milky.

 

This post makes me wonder. Obviously people have fed frozen foods without rinsing and probably not had a problem. But has anyone rinsed frozen food long term and seen any changes in water parameters or fish health? I put a chunk of frozen meysis in my tank this morning for the first time and Ive never seen my skimmer spit out that much fluid. Like what everyone else said, for about an hour. Maybe there are just too many variables to come to a conclusion (amount and how often used, tank size, equipment, whats living in the tank...etc)

 

the reason why the skimmers react the way they do, is because the oils change the surface tension of the water.

As for rinsing and not rinsing health. That would be a good project.

 

They're pulled out of a lake in Canada, so I doubt they're gut loading these guys with anything.

 

Is PE a brand or a type

 

Brand

 

Piscine Energetics Inc - PE MYSIS - fresh water shrimp

their promotional website if anyone cares. according to it no gut-loading, pollutants, salt, or any other additive. So the nutritional part must be from the actual shrimp.

 

It's that they come up for breeding season from deep in the lake once per year, and they catch them then and store them. Breeding season is typically the kind of time when animals have an abundance of extra nutrition, like fats and proteins, to spend on procreation, so they don't need to be gut loaded.
