Most ponds with a waterfall or fountain have some foam or froth from normal water agitation. But if that foam keeps accumulating and does not dissipate, spreading like a white carpet across your pond, it may be a sign of an underlying problem with your pond's water conditions. These stubborn bubbles (white foam) are commonly due to an excess of dissolved organic compounds (DOCs) collecting in a slick along the water's surface. The DOCs can come from many sources including overfeeding, a buildup of fish waste, or decaying plant material. DOCs not only produce unsightly foam, the can also reach a level at which they become deadly to your fish.

If you are trying to solve a pond foam problem, consider these possibilities and solutions:

POSSIBILITY:

Are your pond's water conditions out of balance?

Solution: Use a test kit to check for ammonia, nitrite, and nitrate levels. Trace amounts of nitrate are acceptable, but if any ammonia or nitrite are present, your pond may not be cycled correctly and is out of balance. In other words, there is more waste being produced than can be processed by the bacteria and plant life available. Your pond may need more biological filtration or bacterial additives to bring conditions back into balance.

POSSIBILITY: :

Are you keeping too many fish in the pond?
Solution: High nitrate can mean that you have an overstocked pond or you have not performed a water change for a long time. If water changes are performed regularly, you have 2 choices: reduce your fish population, or reduce the amount of DOCs your filter must process. Reducing the amount of DOCs can be approached in several ways:

Pack your filter with activated carbon. The activated carbon will adsorb the DOCs. Once the carbon has become saturated or coated with suspended solids it must be replaced. Activated charcoal is relatively expensive, so is not the best alternative for larger ponds.

Add many more healthy, live plants. The plants will help to use up the nitrate produced by the fish.

POSSIBILITY:

Is your pond filter too small for the size of the pond?
Solution: If your filter is not adequately sized for your pond's volume, DOCs may be collecting on the water surface. To remedy this situation you will need to either add another filter, or get a larger one; remember it's always safer to use a larger filter than recommended by the manufacturer.

Regardless of the problem and solution, you will still need to perform regular water changes to keep the DOCs under control and the nitrate levels low.

POSSIBILITY:

Have you recently added medications?
Solution: Medications can also cause a waterfall or fountain to foam, although is should dissipate within a day. Since you will need to remove any chemical media such as carbon for treatment, and any foam covered surface area cannot efficiently exchange oxygen, it would be wise to run an aerator during treatment. If possible, it is more productive, safer, and cheaper to treat diseases by removing the fish to a separate container.

A quick solution…

In addition to getting to the root of the problem, there are some "quick fix" products targeting nuisance foam directly. Try a defoaming agent such as Pro-Polish Defoamer, Anti-Foam, or No More Foam to keep the surface of your pond a clear reflection of all your hard work and creativity. These products are deemed safe to use with plants, pond fish, and other animals.

A great solution, regardless of the cause…

A main way of controlling the buildup of DOCs in the average garden pond, regardless of the cause, is to increase the number of water changes. In some geographical areas and in very large ponds, the cost and/or amount of water needed may be unfeasable. In these situations, a foam fractionater or protein skimmer may be helpful. Ironically, a protein skimmer actually uses bubbles to attract protein molecules. The resulting foam is then removed through a disposal hose.

2- How to cure Pond Foam :

How to deal with Protein Froth / Foam

Protein Froth is an unsightly foam which sits on the water surface and can look like some one has tipped washing up liquid in to your pond. Protein Foam is normally formed where the water comes back in to the pond at waterfalls and filter returns, but can also happen around fountains and venturi’s. In most cases it is caused by Protein, which is an oil based chemical that floats on the surface of the pond and makes the bulbs last longer. This oil is a natural chemical and will eventually disperse by itself, the problem is it will take months to do so and your pond can look awful until it goes. Not only is it ugly, but it can be dangerous to fish as well. The surface of the pond is where most of the essential gas exchange takes place, allowing Carbon Dioxide out and Oxygen in to the water, if the surface is then coated in protein oil it can hinder or even stop the gas exchange. So solving this problem not only to improve the appearance of your pond, but also ensures the health of your fish. Thankfully this is one of the simplest things to eradicate in your pond, TAP - Anti Foam Pond Treatment will literally make it disappear in front of your eyes.

TAP - Anti Foam Pond Treatment is designed to breakdown the froth in garden ponds, created by the excessive build up of protein in the pond water. TAP - Anti Foam Pond Treatment is non toxic, harmless to plants, all fish and other aquatic life and does not affect bacterial filters.

Where did it come from?

It helps to understand why it has occurred in the first place, because in some cases it is preventable. The two most common causes for Protein Froth are spawning from fish/ frogs/toads and feeding the wrong type or quantity of food. Spawning is not something you have control over, but you can control the amount and kind of food you feed. If the fish are fed too much in one go, they will wolf it all down, but it will pass through them quickly and much of it comes out as waste including Protein. In the summer month’s food should not last for more than 5 minutes, any more and you will be overfeeding. If you are not convinced that the fish will get enough food this way stick to the 5 minute rule but feed them several times a day. To help you keep an eye on how much food the fish receive you can use a floating feeding ring, these float on the surface of the pond and keep the food in one place. In the cooler Spring/Autumn weather, fish are programmed not to absorb Protein, so feeding them a growth or high protein food at these times of year will mean it passes straight through them and comes out in to the water. Use the low protein wheatgerm foods at these times of year. So the best way to prevent the protein foam from occurring is to feed your fish the correct kind of food for the time of year (and temperature) and to feed little and often.

3- Why Is There White Foam in My Koi Pond in the Morning?

When you have a koi pond in your yard, you possess an attractive and novel feature that can provide hours of enjoyment for family and friends. Although having pond wildlife available for daily observation can be fascinating, the pond requires dedication and commitment on your part. When you awake each morning to find that white foam has formed on the pond, it's time to get to the bottom of the problem.

Koi Pond Basics :

Although a koi pond can be a stunning feature, the most important aspect of the pond is to provide a safe, comfortable home for fish. The Southern Regional Aquaculture Center recommends keeping the water temperature in a koi pond 65 to 75 degrees Fahrenheit. It advises that oxygen levels should be a minimum of 5 mg/L and the pH level should be neutral, at pH 7 or near 7. Koi can survive in conditions that vary from those recommended, but adhering to the optimal parameters decreases the likelihood of foam development in the pond.

Normal Pond Foaminess :

Some foaminess in a koi pond is natural. Bubbles caused by the motion and movement of the fish or by a newly installed water feature such as a fountain or waterfall may cause the water surface to have a frothy appearance. Checking the pond's water visually at several intervals during the day is helpful. Notice whether the morning foam seems to be a result of water or fish movement or something else altogether. Assess whether the foam dissipates during the course of the day or remains undisturbed on the water surface indefinitely.

Spawning Conditions :

When koi spawn, they become quite active and thrash about in the water as the male fish chase the females, waiting for the release of eggs so they can fertilize them. When spawning happens, the pond water is disturbed, and the activity creates a foamy or frothy appearance in the water. According to the Southern Regional Aquaculture Center, spawning typically takes place in early morning. As a result of that activity, the koi pond still may appear foamy later in the morning.

Organic Waste Issues :

A common cause of white foam in a koi pond is excessive amounts of organic waste in the water. Excessive organic waste may be caused by overfeeding of the koi, too many fish housed in a pond that is too small for them or inadequate filtration of pond water. A simple solution to restore the water's balance and remove excess organic waste is to remove and replace about 20 percent of the water every two days until the foam disappears.
