Speed,
I feel your pain, I have been exactly where you are and now my 220 gal is majano free. Just to be sure what we are talking about, if they look like this
"Majano"

or this "aiptaisa"

either way I have had both. The way I have eliminated these pest is to get a syringe, no need for a needle either, and mix up some Kalk paste and cover the head of the pest with the paste, you hear people inject the pest with it, I just covered them with it.
To make the paste, mix some kalk and fresh water together so it has the consistency of white glue. Draw the paste in the syringe and cover the pest with it. I was covering about 50 or so a night for weeks. You may be concerned about covering other living things with the kalk paste, I will tell you that my zoos, scrooms, sps, and lps all recovered if they got any on them. remember its just calcium, but do be alittle careful with your other inhabitants.
If you have majanos, they like the light and will be towards the top of the tank, persistence is the key and you will get rid of them. If you touch the head of majanos before covering them they may come back the next day. It may take awhile and like TOURKID said, do not do all of them at once, it helps to have a partner spot for you while you cover them. I never tried joes juice because I am cheap and I had the kalk. I never sucked the pest up either, but whatever works for you. Good luck
