Problem has been fixed. The little funnels are left on by my nephew and after talking to Adriene at Polly's, i removed them and filters are now quiet as church mice. Needless to say when i asked my nephew [age 4] he started crying thinking i was gonna spank him, he said he was very sorry and he was just trying to help. I told him i wasnt mad and promised to buy him a fish as a thank you.
