On my 250, the hinges that lift the lid (the whold lid, NOT the front or feeding part) are EXTREMELY sqeaky. Am I the only one with this noise? It has been the least of my worries so far as i have been trying to get everything going. What can i use to eliminate this everytime i open it? Obviously anything i spray on it has a chance of seeping into the tank water. My 3 year old sleeps real close to the tank which is why i would like to silence the noise.
