Hello- I have been battling some white slime for months now and cant seem to make much progress. I think from my research it is likely bacteria. I can never get good pictures but it looks similar to this: http://www.3reef.com/attachments/bacteria-png.66221/ I have read that Dr Tims refresh/waste away combo may help with this. I am a little afraid to try the refresh since i have shrimp in my tank and there is a warning on the bottle. Would waste away alone help with this slime problem?
