Hi Trido, I read your post about building an aiptasia zapper using a doorbell, transformer and some other plastic parts. Did you ever get the thing to work? Also, could you point me to the prior references you used for building this thing? I'm trying to find all the documentation I can about various methods using electricity to fry them. I've found some information for projects people worked on later than yours, but am really curious to find earlier articles and perhaps where the initial concept came from. Thanks so much for any information you can provide. Rick
