I finished my pseudo kreisel tank and I'm using it to grow these four ephyra. So far its a total success. The spray works excellently and so does the whole tank. The screen is 1000 microns, meaning that it may be just a little too big for new born ephyra. But anything bigger than that seems to do fine in the tank. So I'm thinking I will raise ephyra in dishes and jars on a magnetic stirrer. Then when the get big enough I can move them to the kreisel. I do realize I built this tank for comb jellies but I don't have comb jellies right now so I'm putting the tank to good use. :D
I have delayed this, but my next post should be on how to build a pseudo kreisel.
