i tried to post pics here of the hair algae growing for wickedmidas, but it said the files were too large. i posted in my gallery though. not good pics by any means, but you can see the big piece of petrified wood covered in it. ill get better pics after i clean the glass today and do a water change. fish love the stuff. ive had everything from dovii to devils and everything in between and all appreciate some good greens. AS DO I. PUFF PUFF GIVE.
