You would need to do a lot more water changes and vacuum the bottom frequently, and that's assuming they would eat it, which isn't real likely. If time is your main concern I highly recomend my method. I spend 5 minutes a day hatching and feeding BBS. My Dwarf Tank takes very little time. Why only 5 minutes? I use the BBS hatching trays carried by Brine Shrimp Direct. It's the easiest thing in the world to use, you get a good hatch rate, the BBS decaps itself, and you can collect several times a day to get the freshest BBS. I would recommend getting atleast two so you can stagger the hatch times. Right now, I'm sprinkling the eggs into one hatching tray about 7:30-8:00 A.M. and harvesting the other one during the day. The next day you harvest from the one you started the previous day and add new eggs to the other one. It's very simple, quick, and easy. There are no bubbling bottles and decaping eggs. If I want to grow some Brine out I'll use the bubbling bottles, but otherwise it is completely unnecessary and more time consuming than is needed.
