i have an acrylic tower thing that you add on to your wet / dry filter. it has bio balls and more bio balls. i also have a 3 ft uv sterilizer w/ out a pump it works sometimes and the but sometimes it doesnt (if your familiar with these things you can probably fix it but i don't know anything about them). anyway all i would like is a small frag of either some bright polyps, some blue xenia, OR a small frag of that blue hard coral that grows to look like little shelves (don't know what its called). just a small piece of any of that and its yours. call or send pm (210)978-6399 joel, thanks.
