I just recently installed a Red Sea Prizm skimmer on my 72 FO aquarium. After three days, it still has nothing but water in the collection cup. Is this right? I thought it was supposed to collect a foamy substance.
If you are getting water in the cup then the adjustments are off and no the skimmer is not working properly.
I am not familiar with the red sea prizm so hopefully someone else can help with the adjustments.
Good Luck !!
