How do you keep tbis stationery on the bottom?

The additional small cleaning spheres inside are reasonably heavy and it sank into my bucket pond without any issue and doesn't move. Mine is attached to a floating solar powered aerator which can float but doesn't, as it's anchored by the sponge filter.

Do you sell the sponge filter that are inside.

You can just jeep rinsing the sponge that is within the filter .. this way your keeping the beneficial bacteria within the filter. Please only use your fish tank water to rinse.
