Hi and thanks for the welcome.I do have a few different species of macro and coraline growing everywhere.I generally just vacume them up using a magnum 350.(part of my maintenance tools)and many of them usually burst.I know I shouldn't burst them but I thought that if I could get as many as I could with one go I could also trap their spores in the filter.Needless to say it did not go as planned and now that my "holiday maintenance break" is over I have many many more valonia to deal with.Any other "critters" that may help me?
