Hey you guys I am going to set up a 150 and going to transfer everything from my 120. I have sand in my 120 but I'm thinking of going bare bottom. I always hear that there's probably a lot of maybe possibly toxic gases in my sand. the 120 has been set up for year-and-a-half. I'm also thinking I can have better control of my detrius, by being bare bottom. I want to know what your guys experience is with bare bottom tanks. I've never done that before. I hear there's a material alled starboard,you can put at the bottom it's like vinyl like cutting board material to protect the glass. I think it would probably look better than just glass on the bottom also. Please let me know your thoughts and experience, I appreciate it.
