Yeah they are fast growing, they covered one of our ponds like crazy and my friend who I gave a few to was complaining about them after a few months!
I am wondering that because Rich (if I read it correctly) mentioned that they really don't contribute much to Aldro maybe we should consider not putting them with Aldros? Then again why fix something that is working in your pond at least!
My brother will not like it when I do take off all those javamoss in the pond too!
