Hi I recently got a 75g tank and filled it with fresh water to see if its all running and if there's any leak. However when I tested the skimmer (jad wg 520) some Chinese brand, there was no bubbles (I even removed the airline adjuster to make sure there isn't anything blocking it)
what would cause it? It's brand new
