Pure "vaseline" is safe. Typically a rattle means there's a problem (the lid doesn't count, lol)Otto1 said:I have an aquaclear filter that rattles at times. I have came to the conclusion that I want to use silicone lubricant. However, I can't find any that say they are aquarium safe. So what do y'all use to prevent rattling noises or maintenance the filter? Any suggestions would be helpful
You should use only food grade grease ! I bought this from Amazon very cheap - Haynes( lubri - Film ) 4oz. Tube . It is sanitary, non toxic , odorless, tasteless. It is industrial use , used in many food related equipment. I use it on all my filter o-rings . Doesn’t break down . Don’t get ripped off from buying a tiny tube of grease from the filter manufacturer . Haynes Lubri-Film is perfect .Otto1 said:My impeller is rattling on my aquaclear, and I was looking on the internet for silicone grease. Then, I came across on Danco Silicone faucet grease. Will this work great for the motor and is it plant and fish safe?
