Not sure if this is the correct place to post, but I am trying to remove filter sock section of the Sump on my Red Sea Reefer 425xl. I have razor blades, but I am having trouble figuring out how to take out the black plastic filter sock portions. Can anyone give me some tips on how they did it?
Also should I put silicone down where the class meets the bottom of the tank?
