@ Arno: good idea! 😛
@ AJ: if you click on the register card “search” above and search for “Atemia methods ” you will find an older thread concerning that subject.
I can add here: since about a year I use one JBL cone for breeding BBS. I have two of them. Every second day I make a new set. One cone I feed to all my fish in two days. I put half of the harvest in the breeding mineral sea-salt water (for sea water tanks) in the fridge.
When I open the cone, first I fill a small cup (about 40ml) with the first output, that are mostly unbread cysts..
I rinse them under tap water with a fine sieve about 155 micron openings as Dick says (at the moment I do no more sieve with three ones …)
