"I have a baby painted turtle (he's the size of a quarter) and the waterfall scared him at first. He actually had a hard time swimming across the current & got sucked down to the bottom & it tossed him around. But he got used to it & now he doesnt mind it.
I feed him baby shrimp & mini Krill and the filter sucks everything towards it, so I have to shut the filter off so he can eat & the food doesnt get sucked up. I also have to remove the clogged food from the filter slots at the bottom almost daily.
I did NOT notice a difference in water clarity or tank cleanliness after using this item. Maybe it is working & I just can't tell!?"
