anyone ever think the screeching noise the aglea scraper makes is bad?

Kinda like the fingernails on a chalkboard nobody likes it.....is the same noise bad for the fish?

Stick your head in the water and listen to what it sounds like under water. Maybe it's not so bad?

It probably sounds like a ship sinking along an iceberg or something.

I wouldn't think it would be detrimental to the livestock at all, as long as it's just once and a while when you're cleaning the glass.

That's not the scraper making the noise. That is the sound of millions of algae cells crying out as they are forcibly ripped from the glass.
