What Does Your Pond Need?
Whether you’re choosing plants, fighting algae or upgrading equipment, start with the part of your pond you want to improve.
Pond Plants
Discover hardy, beautiful plants for clearer water, healthy fish and a thriving pond ecosystem.

Stop guessing. Tell us a little about your pond and start narrowing down plants that fit your climate, light conditions and pond setup.
- Review winter hardiness for your USDA zone
- Choose species suited to sun or shade
- Find options for koi and fish ponds
- Build a healthier, more balanced ecosystem
Tell Us About Your Pond
Four quick details will help us point you in the right direction.
Your next steps
Check the exact species or cultivar, mature spread, crown-to-water depth and local invasive-plant guidance before buying. A hardiness zone alone does not guarantee survival in a pond.
Plants That Work Hard and Look Beautiful
Great pond plants do more than decorate the water. They provide shade, absorb excess nutrients, shelter wildlife and help create a naturally balanced pond.
Water Lilies
Iconic pond plants that shade the water and bring spectacular summer flowers.

Pond Irises
Strong vertical foliage and beautiful flowers for pond edges and shallow shelves.

Start at the water’s edge
Think in layers: a planted edge, suitable aquatic plants and enough open water to enjoy the reflections. Your pond’s light, depth and available space help shape the plan.

Healthy ponds rarely need guesswork. Start with the symptom, understand the likely cause, then choose the simplest solution that restores balance.
Green Water
Pea-soup water is usually associated with suspended algae benefiting from available nutrients and sunlight.
Clear green waterString Algae
Long green strands often indicate favorable light, available nutrients and suitable surfaces for filamentous algae growth.
Control string algaeCloudy Water
Murky water can result from suspended debris, disturbed sediment, inadequate solids removal or biological imbalance.
Diagnose cloudy waterLow Oxygen
Fish gathering at the surface or near moving water can be a warning sign of low dissolved oxygen and should be investigated promptly.
Improve oxygen levelsNot sure what is wrong with your pond?
Start with the symptom and work toward the cause.
Pond Equipment That Earns Its Place
Good equipment solves a specific problem. Learn what each component actually does before spending money on gear your pond may not need.
Pond Filters
Remove suspended and settled debris, provide surfaces for beneficial microorganisms and support more stable water quality.
Pond Pumps
Move water through filters, waterfalls, streams and other circulation routes within the pond system.
Pond Aerators
Support gas exchange and dissolved oxygen for fish, microorganisms and the wider pond ecosystem.
UV Clarifiers
Expose circulating water to ultraviolet light to help control the free-floating algae associated with green water.
Not sure what equipment your pond actually needs?
Start with pond size and the problem you are trying to solve. Bigger and more expensive does not automatically mean better.
Useful Pond Tools for Better Decisions
Use quick, practical tools to estimate pond volume, choose a suitable pump size, review fish load and plan healthier plant coverage before buying equipment or treatments.
Pond Volume Calculator
Estimate how many gallons your pond holds so you can make better decisions about filtration, pumps, treatments and fish load.
Pump Size Calculator
Calculate delivered flow from water volume and your chosen turnover interval, then check the pump curve at actual operating head.
Fish Stocking Guide
Review fish load before overcrowding contributes to poor water quality, inadequate oxygen or excessive filtration demand.
Plant Coverage Planner
Convert your chosen surface coverage percentage into an area, with clear guidance on what the estimate includes.
Practical tools first. Better product choices second.
Understand the pond before spending money. Once you know its volume, circulation needs, fish load and planting goals, choosing suitable plants and equipment becomes much easier.
Build the Ecosystem Before Buying the Solution
A healthy pond is more than water, fish and equipment. Plants, microorganisms, oxygen, nutrients and circulation work together. Understanding that system often leads to simpler, less expensive and more natural solutions.
Understand the Cause
Green water, algae, unhealthy fish and weak plant growth are symptoms. Begin by investigating the conditions creating the problem rather than immediately adding another product.
Use Nature First
Suitable plants can provide shade, use available nutrients, create habitat and support biological balance. Equipment should strengthen the pond system rather than attempt to replace it.
Buy What Solves a Problem
Bigger pumps, expensive filters and repeated chemical treatments are not automatically better. Define the task first, then choose equipment that genuinely earns its place.
Practical Guides for a Healthier Pond
Understand what is happening in your pond before adding another treatment, replacing equipment or changing the ecosystem that is already there.
How to Clear Green Pond Water Naturally
Learn why pond water turns green, what algae may reveal about the ecosystem and how plants, shade, filtration and nutrient management work together.
