Aquarium Advice FINatic
Everytime I do a water change or top off my water, the collection cup fills up with almost the same amount of water that I just put in. I turn off the skimmer usually for a day after I add water but it will still fill up at least 2 cups with in the hour. After that it will be fine but then I need to top off my tank again. I put it on the driest skim it can do and still fills. Anyone else having this problem? Any tips? TIA!
