First your microworm culture.
Immediately make another one. Use a rectangle takeaway container and crush up 2.5 weetbix. Moisten and grab a spoonful of other culture (full layer of old culture), place this on top of weetbix. Cover in a good amount of yeast. About two weeks and this will be teeming. Repeat again. That way there is no original mixture in your new culture. Weetbix doesn't smell anywhere near as bad. :-).
Bbs.
Best tip here is get GOOD quality eggs. I use coke bottle method. Takes ten minutes to make. I run two at a time and always have bbs ready to feed. Even my tetras eat bbs. :-). If you need a photo, I will take one for you.
Just have a go. I was hesitant about it, never used live food before but its fantastic and cheap. :-) Ps, my mixture for bbs is
Approx 1ltr water.
I tablespoon of sea salt flakes, stirred in.
Half max of teaspoon of eggs.
No light other than room light (kitchen bench) and no heat (but I live in Brissie).
36 hrs and I have heaps. 48 hrs in winter. I suck them up with a syringe and airline and squirt that, as is, into the tank. Usually get two feeds per mix. That's feeding two or three tank with various amounts of fish/fry.
