Recurring Algae Every Summer
If green water returns every season, the pond likely needs a system correction.
- Aeration for oxygen
- UV for suspended algae
- Bacteria for waste control
Large Pond or Lake
Larger ponds often need stronger aeration, diffusers or surface aerators.
- Airmax pond aeration
- Kasco surface aerators
- Diffusers and air stones
Recommended Green Pond Water System
A single treatment can help temporarily, but long-term clarity usually comes from combining the correct products for oxygen, algae control, filtration and biological balance.
1. Add Oxygen & Water Movement
Use pond aerators, aeration kits, diffusers or air stones to improve oxygen and reduce stagnant water.
2. Control Suspended Green Water
Use UV clarifiers for pea-green water caused by suspended algae.
3. Support Biological Balance
Use beneficial bacteria to help process organic waste, sludge and nutrient buildup.
4. Improve Filtration
Use pond filters, pressure filters and filter media to support long-term water clarity.

Open CalculatorWhy Pond Water Turns Green
Green pond water is usually caused by suspended algae multiplying in the water column. Warm weather, direct sunlight, fish waste, decomposing leaves, runoff, low oxygen and weak filtration can all contribute to algae blooms.
For long-term water clarity, the goal is not only to kill algae. The goal is to reduce the conditions that allow algae to keep returning. That often means better oxygen, filtration, UV clarification and beneficial bacteria support.
Frequently Asked Questions
What is the best product for green pond water?
For pea-green water caused by suspended algae, a UV clarifier is often one of the most effective product types. Water clarifiers and beneficial bacteria can also help support overall clarity.
Will algae treatment fix green water permanently?
Algae treatments can help reduce visible algae, but if the pond has low oxygen, excess nutrients or weak filtration, algae may return. For recurring green water, consider aeration, UV clarification, filtration and bacteria support.
Do I need a pond aerator?
A pond aerator helps improve oxygen and water movement. It is especially useful for stagnant ponds, ponds with fish, ponds with bad odour, and larger ponds with recurring algae or sludge buildup.
What should I buy for string algae?
For string algae, start with algae control products and physical removal when possible. Long-term improvement may also require better aeration, lower nutrient buildup and stronger filtration.
Do you ship pond water treatment products in Canada?
Yes. AquaGarden sells pond water treatments, pond aerators, UV clarifiers, pond filters and related water feature products online with shipping across Canada.
