Answers to your most common pond questions

Helpful Tips & FAQs

Explore our frequently asked questions to get practical advice on planning, designing, and maintaining your koi pond. Each accordion item provides clear tips and insights to help you make informed decisions for your pond project.

1. How do I control algae?

Algae growth can be managed with regular cleaning, proper filtration, and water treatments that balance nutrients. Adding aquatic plants also helps compete with algae naturally.

2. How long does it take to install a pond or a waterfall?
A small waterfall (about 2 ft high and 3×3 ft wide) can be completed in around 2 days. Medium-sized projects usually take 1 week, while larger custom builds may take up to 3 weeks, depending on design and materials.
3. What do you recommend for a small space?
A custom fountain or compact pond is perfect — they create a relaxing ambiance without taking up much space or requiring heavy maintenance.
4. I want a waterfall, but my yard is flat. Is that possible?
Yes. We can build a base using retaining concrete blocks and create an artificial slope to make it look naturally elevated.
5. When should I use a concrete or plastic pond liner?
It depends on the design and vegetation. Plastic liners are flexible and more affordable, while concrete liners are durable and best for larger, long-term ponds or waterfalls.
6. Do waterfalls require a lot of maintenance?
Not really. A light monthly cleaning is usually enough to keep the water flowing and algae-free. Larger waterfalls may need servicing twice a month.
7. Will a waterfall affect my fish or plants?

No — in fact, it improves water quality. The constant movement adds oxygen to the pond and helps keep the water clean and healthy.

8. I want my pond to stay crystal clear and never turn green. Is that possible?
Yes, but only if there’s no aquatic life. Keeping the water perfectly clear requires chlorine or other chemicals that prevent fish and plants from living in it.
9. Do I need a permit to build a pond, fountain, or waterfall?
It depends on your city and project size. Most small residential features in California don’t require permits, but larger builds or those with electrical connections might. Always check your local and state regulations for confirmation.
