Hi...was just making an order on line and I see the site has algae (which I need to get for my fuge)....They sell....Halimeda, Feather Caulerpa, Caulerpa Racemosa, and Red Grape Caulerpa. Anybody have experience with any of these and will they work in my fuge? I'm ordering enough other stuff to get the free shipping and thought I would throw this in for the (*&% of it.....Thanks
