So I take it you need a 25 foot cord? Or what size exactly do you need? And you should add fish..they are such great pets :)

Look up Aquasurge Pump--it has a long cord along with AquaForceTM--which also has 25 foot cord..I own a Aquasurge pump and love it..both come with 3 year warranty .

I am looking for around 1000 to 1500 gph with a 25 foot power cord. I have another pond with fish, this new pond is only for frogs and other wild life.

The Aquasurge Pump is way too big for my needs.

Why not just buy the pump you want and a heavy duty extention cord? I like pondmaster Mag Drive pumps the best. They come in all sizes and hold up for years and years.

If you really want to follow electrical code, you should run a buried conduit to the pond location and then use a shorter cord. Permanent extension cords are not really the safest way to go.

I do have a outlet by the first pond. The second pond I am building is about 20 feet away from the outlet. I am not comfortable with an extension cord since I need the pump to run 24/7

Even though it might not pass code, I have been running water and air pumps on extention cords for many years, 24/7. The key is to use a heavy cord, not a lighweight household cord. They do make cords that are rated for outdoor or landscape use.

If you dig a trench at least 18" deep you can run conduit from the 1st pond outlet to the new pond. If you don't use conduit you can use UF (underground feeder) wire directly in the ground but need to dig 3'. You wouldn't want to accidently dig into the wire when you add a 3rd pond now would you. If you are not comfortable, you can dig the trench and then get an electrician to come in. The digging is labor intensive, and when I do work I tell my customers that you don't want to pay an electrician to do laborers work.
