How do you replace the built in sponge filter?

I'm not seeing replacement sponges on Amazon or on the hygger website. If you rinse it out good with your water changes it should last a long time, otherwise you might have to get a generic sponge and cut it to fit. To be honest, I'd probably just buy a whole new filter at that point since they're cheap and the sponge it comes with should last a long time.

My tank came with a small submersible air pump. Would a submersible pump work with this filter?

if you can connect an air tube it will

I don't want the bio balls what can I replace it with?

bio balls are very beneficial to the quality of the water

Malísimo producto

Malísimo, primero no explica que debes comprar adicional una bomba de aire y aún cuando la compras el conector de la manguera está tapado por lo que no permite el paso de aire por ningún espacio. Tiene error de diseño o algo similar dado que es imposible qué funcione
