I feed about 9 tanks and use a pipette. After I rinse the baby brine I pour them into a glass yogurt container I have. It's a little bigger than a baby food jar. I do this because it concentrates the baby brine so thick in the little pipette it turns completely orange when I suck them up.
My rational for this is, I feel like I'm putting more brine than water into the pipette and when I put it into a tank I am able to put a copious amount of brine with just a tiny pipette.
