Hi I joined this site about 3 or 4 weeks ago. I posted a question in the sick fish part. I got alot of help from you all. I just wanted to say that I was sorry for not getting back to you all. I have got cancer and have been taking chemotheropy treatment, may not be spelled right. But I love saltwater aquariums. I have a 220 semi-reef I guess you would call it. I started with a 75 them a 90 and now moved up to my first. big tank. I really like this site because there are no stupid questions. I do not me it like that but if someone asks a question the others answer it and do not have a attitude. I have been doing saltwater for probly 10 years and I have questions all the time. Thanks for letting me be a part of it.. I will try to hel as much as possible and ask for help when needed. Good day to all. Kevint
