    they are getting worse and are starting to spread, nuking the rocks are not an option so what is the best method that you have found to overcome this pest

    I've seen people mix up kalk with tank water to make a thick paste then use a baster/syringe to apply the paste to the hydroids. that would be a lot of work if you have a large number, but it works well. sometimes it takes 2 applications though.
