I looked again at your algae picture, and I noticed a hydra attached to the algae. The algae looks a lot more "spread out" than the Cladophora that I know, which is very bushy. However, it does have more side branches than the other long tough hair algae that I know.

I use the bleach treatment to keep my plants and tanks free of hair algae. Hopefully, some time in the future, aquatic plant sellers will certify that their plants are hair algae free. In my opinion, that would increase the value tremendously.
