Sorry but Keep at it! You'll get it!
Once they hatch, add an airstone if you're not already using one and turn down the flow to point to where they are
not drawn into the current and get tumbled around. I find this to be much easier in a long 10gal tank instead of a small 5 gal or other 'short' tank.
Phyto is enriched with zoecon so that should fatten them up
What do you mean by that?
Never add zoecon directly to the larvae tank. It is very oily and can create a film on top of the water that can kill the babies (I think they suck it in somehow and suffocate).
Just use the instant algae to feed your rotifers. It works perfect.
Also, make sure you're seiving the rotifers. Never add rotifer water to the fry tank!!
