Skimmer for mini aquarium

This is skimmer for Mini Aquarium. You need to fill skimmer with filtering materials like sponge or cotton and once its fitted to aquarium and adjust the height of skimmer with
water level of aquarium.

For motor I am using 3-6v DC submersible Motor (search for "3-6V DC Mini horizontal submersible pump on amazon/ebay). I have soldered motor cables to 'USB type A' so
that it can be powered using mobile charger or power back when needed.

Note: Do not switch on when feeding!!!
