You're skimming a little wet. What it collects should be a bit thicker and darker. Wetter = Lighter color skimmate, Pulling out more nutrients. Dryer = Darker Skimmate and leaves in more nutrientsThis will be the 2nd time I empty my cup in less then a week…I’m wondering if this protein skimmer is just too strong for a 40 gallon ? Can it possibly taking out the good nutrients ? I’m about to give up on tiny tanks as I found my larger tanks give me way less trouble lol
