For 2 days in a row, I'm getting less than 10% hatch rate. Previously I am getting around 50% to 60% hatch rate (which isn't very good to start with) for the OceanFree Brine Shrimps Eggs.
Didn't changed any of the variables. I use around 1.5g of salt of about 800ml of de-chlorinated water with 3/4 of a teaspoon of eggs. Stored the reminding eggs in the fridge.
What I'm trying to push here is always have plenty of microworms or other food source as a back up. Microworms are a stable and sustainable food source. As long as you have at least 3 cultures running, you know that your fry will always have readily available food.
Note: Hatch rate gauged by visually comparing the amount of sunken unhatched eggs with the amount of floating egg shells.
