Now that my phosphates are down to an acceptable level (thanks to my new RO/DI), I've decided to rip out all of my crappy, overpriced, LFS LR and order 60 lbs or premium coraline rock from Dale at gulfview. I have hair algae on my rock now that is slowly going away. Once I rip this crap out, I shouldn't have to worry about it comming back on the new rock if I keep the nutrients out of the water, right? Also, my favorite multi-colored colony rock has been growing hair algae like crazy since I upgraded to MH. It's very hard to manually pull it off the rock since the zoo's are all over. Should I just frag off all the polyps and put them on the new rock?
