Does the filter tube extend? Does the water have to be filled to the top to use?

Yes, it includes the additional tube to extend. It will be better to fill filter case completely with water before it starts. Otherwise, it will take some time to pump water up. (Water must at least cover the motor.)

What if the filter doesn't start or makes a mechanical noise?

Try to turn the impeller by hand. Check to see if something is jammed in the impeller. Rinse impeller and filter to remove blockage.

After a powerout, will this filter restart on its own?

Yes, the motor will restart by itself once the power turns on.

Can I use this in a turtle tank?

It is not recommended for turtle tanks.

Does this filter fit on a framed aquarium?

Yes, you need to gently pull the intake tube to hang on your framed aquarium. The width between intake tube and housing is 0.4 in.

Very bad product

This product is one of the worst products I have bought. If you need my evaluation, I will give it a bad evaluation because it broke down in the first week and when I started using the product, it was very hot. I do not advise people to buy it and I advise them to buy any other product.

Great little filter. Effective and silent. Unfortunately stopped working after a week and I followed all instructions precisely.

Product came broken with a lot of scratches

Very disappointed. The product that I received came with a broken motor propeller. There’s a lot of visible deep scratches in the surface even though it was well packaged (Product box with bubble wrap within another box). It seems I was given an already used item.
