While this is a forum and it is a casual place to come and have fun and enjoy our hobby, there are fundamental things that we must use in our daily post so we do not come off as being illiterate, you dear need to polish up on your spelling, unless of course your first language is not english, if this is the case I appologize. If it is then please by all means and for the people posting and also asking questions here, ie; seeking help, PLEASE grab your dictionary and give an effort.
Good luck with the discus, IF you're getting them so cheap you might want to ask yourself WHY they're so cheap...
