that sucks about your sump and the ich outbreak. when i had my 29 gallon i use to get ich and i tried cleaner shrimp and it didnt do anything lucky for me petsmart sells a reefsafe ich treatment that works pretty well, when i upgraded to my current 55 gallon reeftank i was lucky when i got my new cleaner shrimp cuz now whenever my fish get ich they usually only have it for a day or two.
