Hi - aquarium newbie here. I've had a 55 gal
freshwater aquarium running now with cichlids, liveplants for about 3 months now. All healthy. I have been running a Fluval C4 filter (bought new) and a few days ago I noticed water on the floor. It is dripping (1 drip every 10 seconds) from the back right lower corner (as you face the tank) of the unit. I've taken it off, cleaned everything using distilled water, put it all back yet it still starts that drip. I don't see any cracks in it. Any advice on what I should check for?
