That would be Super Skimmer 65....
Have you added any water conditioners, red slime algae removers (or slime algae removers at all), medications, anything like garlic extracts (oils), or have you done a large water change (50% or more) with freshly made saltwater? Has anything died in the tank recently, are there any fish such as soap fish (that produce a lot of slime) in the tank, any species of nudibranchs in the tank, new live rock, is this a new set up or a newly set up skimmer on this tank?
If you can list your tank stats (how long tank has been set up, how long since adding the skimmer, what animals are in the tank, etc) that would help alot to sort out what is causing it. Once we discover the cause then we can move on to how to fix it.
Sorry for the amount of questions but there is no other way to help... |
