Freezing Brine Shrimp

I haven't seen the live stream but I can say that I have been freezing my baby brine shrimp then later feeding them to my white clouds and betta and am having no problem. I dispense the shrimp into a container and throw it into the freezer. Later when I need it I run it under cold water in a net to de-thaw the shrimp. I haven't yet just chucked the ice puck in the tank but I am tempted to.

I actually do both! I have a bunch of eggs in the freezer because I only use a little at a time, and I’m trying to get them to last. I also put baby brine shrimp in ice cube trays and freeze them. I put a whole cube in my larger tanks, and to feed smaller or more fragile babies I’ll melt the cube in a cup of warm water, let the shrimp settle to the bottom, and pipette the shrimp into the babies’ tank.

I found at the dollar store one of those silicone ice cube trays that makes small cubes, about a half inch cube. When I do hatch brine shrimp I will hatch so I have extra, and I will put a squirt in each cube then add some clean water and freeze. The next day, after i freezes, I will pop out and put the cubes in a zip lock bag and keep in freezer, then can feed when I want.

I first feed my tank once my batch hatches. I freeze the leftover as is - no rinsing. The salt helps the plants, like Cory has stated. 

No rinsing for me.

I think that's only maybe true if you use sea salt/reef salt.  I've never heard of anyone adding sodium chloride to a tank to help plants.

Edit: I forgot to mention that at least API "aquarium salt" is pure NaCl.  I assume its the same for fritz.  And even sea salt is 90-99% NaCl.

 

Setting brackish tanks/plants/fish aside for the moment, I've never heard of Na+ or Cl- being an essential mineral for freshwater aquariums.  Of course fish and plants need some sodium, but sodium is so ubiquitous there's enough already in your food and water.  Also it says on the bag that some plants may be sensitive to aquarium salt (presumably in the doses they suggest).

 

That said, the 25mg of salt form 1ml of bbs you'd put into a fish tank is probably trivial assuming you do water changes occasionally.
