Any recommendations for outdoor air pump?

Hello guys,
Any one have a recommendation for outdoor air pumps? Preferably one with 2 outlets as my dad has two fish tanks (each are 20 gal) next to each other. Currently, the tanks use an indoor-use pump placed inside of a plastic box, but I'm not sure if that's safe so I stopped using it.

Many thanks

 

Sorry i have no reccomendatins for outdoor air pumps as ive never used one but they dont nessecarily need 2 outlets it can have one outlet and then add a split valve.

 

I have a large air pump in the garage pumping into a 1/2 inch irrigation hose. The hose runs across the ceiling space down into the fish room around the room and out the window . Then across the garden and under the deck to outdoor tubs. I am guessing there is about 45 feet of hose or more. That is my suggestion for you.

You can get solar powered water pumps to run a basic filter but I have not seen a solar powered air pump.

Do you have an outdoor power supply/ power outlet/ power socket?

The outdoor pond air pumps I have seen are exactly the same as any pump . They are not water proof. You can put them in a box like your dad did, but the power cord and plug is still outside in the weather. A dangerous thing?

Edit
Well surprise surprise, is interesting what you can find on sale .
Thanks user35789 I would not have found this just by asking my local shops.

A dangerous thing?

I sometimes run a small power head type thing for airation and extra flow in my outdoor pond, I have water proofed it as best I could, taped the plugs together **** half a roll of duck tape, sealed in may pony bags, put into an outdoor water proof box and some how water still gets in from morning dew and trips the power in home, happened 4 times now, I don't use it anymore

 

Three litres per minute is enough to run two sponge filters ( almost)

20W Solar Powered Panel Air Oxygenator Pump for Fish Pond Outdoor Pool

 

Sorry for the late reply, I didn't get a notification.
There are 2 waterproof outlets right by the fish tanks. I'm also pretty sure that my parents wouldn't allow a line to run indoors to outdoors if it was through the window or via drilling a new hole in the wall. I will consider the solar powered panel (if it comes back into stock) if there are no other suggestions.

Thanks for the help
