Hi everyone, I'm doing my senior project and have just successfully bred my bettas and hatched some gardneries. So I started hatching some brine shrimps for the fries. The specific gravity is 1.02 and the pH is over 8.0 the room temperature is around 70 degrees. The first batch was very successful and the shrimps survived for over five days after hatching within 30 hours. For some reason the second hatch died within a few hours even thought the water is new but from the same mixture I had made for the first hatch. I'm using a Wardly's pH up, with regular ocean salt Susan gave me and hatching the shrimps in a cut bottom 2 liter bottle. A regular air stone is used to supply the air current. Could there be not enough air in the water because the shrimps died two hours after I removed the airstone to collect them. Is temperature an issue?. If anyone can help, that would be great because my microworm culture is not yet ready and the fast growing fries really need their food. Thanks Thai --------------------------------- Do you Yahoo!?
