For now, just let it drain back into the tank. You aren't actually skimming anything at this point so no reason to waste the water.Right now the I have the drain line plugged because it was draining way too much water for me to feel comfortable to just leave it while I'm off at work or school (I leave my house at 5 am and not back until 10pm). Im going to raise the skimmer to 7 inches when I get home today, and I guess I will try attaching the drain line to some left over air line I have laying around and then to an empty 10 gallon tank so at least it wont over flow.
