Easy DIY Solar Fountain in 1 Hour! {with Pond Water Plants}

I can’t believe how easy this DIY solar fountain is to create! With all the beautiful pond and water plants, and the sweet bubbling sound of water, it makes us feel that we are sitting by a little creek in the mountains.

Everyone loves garden fountains and patio ponds. But they usually require lots of work to set up plumbing, electrical, etc. Made from an old galvanized tub and a simple solar fountain pump, this outdoor solar fountain ( birds love it too like a birdbath! ) is so easy to build and maintain. Enjoy it all year round, or in colder climates, move it easily to a protected location when the temperature drops below freezing.

So excited to share with you today how to create a simple solar fountain easily with or without water plants!

Don’t miss the Helpful Tips section at the end on choosing vessels, solar pumps, adding aquatic plants or fish, and how to keep your solar fountain water clean and free of mosquitoes. 🙂

Materials needed to make an outdoor solar fountain or bird bath:

Step 1: start with water and plants

After selecting the location for your outdoor solar fountain or bird bath, it’s time to add water and aquatic plants. Pond and water plants are optional, but we added them because they are so beautiful. Plant roots also help keeping the water clean and free from algae.

Fill the tub halfway with water. You can add more water after all the plants are placed inside the tub.

In the Helpful Tips section at the end, I will share more about what type of soil or pots to use for pond and water plants. In short, use plastic nursery pots, and avoid rich potting soil. We also topped the pots with some rocks which looks pretty and prevents anything floating up through the soil.

There are many beautiful and easy to find water garden plants. Here we used Cyperus involucratus “Baby Tut”, Taro, Canna Lily, Siberian Iris, and Loriope. These are emergent type water plants.

We also added water lettuce, which is a floating type water garden plant. Its massive root can clean the water really effectively. We can stop at this point with our lovely mini patio pond! However, the sound of water is just too irresistible…

Step 2: Add solar fountain pump.

This 1.5w solar pump  (here is another one that is similar ) has a 10 feet cord from the pump to the solar panel so you can place the panel in the sun but out of sight!

This pump does not store solar energy, which means the fountain will be off when the sun is not shinning on the solar panel.

Helpful Tips and FAQs

Solar fountain pump choices and considerations.

When creating an outdoor solar fountain, pay attention to water splash radius, which will affect where you place the fountain and other furniture and decor items.

IMPORTANT: always keep the pump submerged in water when its running. When making adjustments, face the panel away from the sun until you can keep the pump submerged in water. Otherwise the pump could burn out.This applies to both the solar pump we are using and  the floating type solar pumps like these.

Solar fountain vessel choices and considerations.

In addition to  galvanized steel tubs, you can also use a half barrel or any containers that hold at least 3″ deep (see solar pump) water and are designed for outdoor use. This vessel depth will accommodate most small pumps.

How to keep your solar fountain water clean and free of mosquitoes.

Algae grows where there’s lots of sun or nutrients in water. Place the fountain in shade, or use plants to shade the water. Plant roots will also use up nutrients. I will write more about water and aquatic plants in another post to give you all the details and variations!

Mosquito larvae can only survive in stagnant water. If the fountain is running often, it will deter mosquitoes. You can also introduce small fish, such as goldfish or mosquito fish, into your fountain to feed on any new mosquito larvae and remove algae as it forms. 

Our reader Sue wrote me a really thoughtful note about how galvanized tanks can harm fish because the zinc in the coating can leash into the water. Zinc is good for plants, but can hurt fish. Here are a couple of solutions:

Fish often do better in old or aged galvanized tanks. Fill a new tank full of water, feel free to add plants, and let it sit for 6 month to a year before adding fish. Start with tiny fish like goldfish or mosquito fish, which are much tougher than Koi. Another way is to line the galvanized tub with pond liner if you want to have fish right away.

If you choose to have plants, here are some soil choices for pond and water garden plants: clay soil is best. Garden soil is fine too. Potting soil contains wood chips and perlite which may float on the water. Avoid rich soil with manure content, as they could cause the water to smell, or become too acidic.

  1. I love my washtub pond, but I got mosquito larvae quickly. Somebody suggested buying some feeder goldfish. My galvanized tub is brand new, but, on a suggestion, I added ten feeder goldfish ($.25 each) about six weeks ago and they seem to be flourishing. They are quite hardy. No mosquito larvae anymore. Also, there is a non-toxic product called Mosquito Dunks that doesn’t harm fish, pets or plants, but kills larvae. It’s made from a harmless bacterium not unlike that found in yogurt. Google it.

    I have a question; does the water ever need to be changed out?

    • Hi Bill! Sounds like your pond is a healthy mini ecosystem! 🙂 in that case, you don’t need to change water. However, in a man-made small water garden, sometimes fluctuations in temperature, vegetation or sun etc can tip the balance, and that’s when something doesn’t look right, and time for us to change water.

  2. I love this idea . However, I have an old cast iron pot (!witches pot). Thinking that would be nice on the front porch. Would fish be ok in that kind of pot?
