I used a different method very successfully. In a small tank (around 15litres) I hatched around 80 eggs. Once a day I lowered the water level to an inch, cleaned the bottom with a turkey baster, and fed BBS and microworms. After an hour I topped up the water to around 8 inches with dechlorinated at the same temperature. Lost only an occasional larva. At front leg stage I added white worm and chopped defrosted bloodworm to their diet for the larger ones.
