Why is my water foamy? | Decorative Ponds & Water Gardens Q & A

Q: Why is my water foamy?

Q: Why is my water foamy?

Luke- Belen, NM

A:  Is foamy water making your pond look more like the inside of a washing machine than an aquatic oasis? All that bubbly white or gray buildup is likely being caused by an excess of organic material in the water.

Accumulation happens when too many fish are living in the pond, you’re overfeeding them, filtration is inadequate or there’s runoff seeping into your water garden. Then, as the water flows down your waterfall, air and water collide, causing the proteins and other organics to be trapped inside bubbles rather than turning into ammonia and nitrites. Air-water collision is why the foam forms, particularly the base of your waterfall.

What’s the solution?

Short-term, you can change out part of the pond’s water to remove the foam. When you do, be sure to add some The Pond Guy® Stress Reducer PLUS to the fresh water, which will form a beneficial slime coat on your fish and make tap water safe for them. In addition, add The Pond Guy® Defoam™ to your water. Safe for fish, plants and wildlife, you simply shake the can and pour its contents into the pond. The foam will disappear in no time.

Long-term, you have several options:

  • Increase Filtration: Boost your filtration by adding plants to your pond or increasing the capacity of your existing filtration system.
  • Relocate Fish: Too many fish will produce excess waste, which means more foam. The rule is to allow 1 inch of adult fish per square foot of surface area, so if you have too many koi or goldfish in your pond, you might want to think about finding new homes for some of them.
  • Cut Back on Meals: If you’re feeding your fish too much or too often, the excess food adds to the extra organic material in your pond’s water. Only feed your fish an amount they’ll eat in a few minutes.
  • Add Nutrient-Eating Bacteria: To help break down the nutrient load in the water, add beneficial bacteria in such as, LiquidClear™ to work. They digest the dead organics in the pond, making the water crystal clear and foam free.
  • Aerate the Water: Aeration will also help reduce the nutrient load by circulating the water column and feeding fresh oxygen to the busy bacteria.

Foamy water can be a nuisance, but once you achieve some balance in your pond’s ecosystem, those bubbles will disappear in no time.

Water Gardens & Features Q & A

Q: Foam seems to buildup on my water’s surface. What is causing this and can I get rid of it? – Tom of Ohio

A: Have you ever walked out towards your water garden and noticed a bunch of foam around where your waterfall comes into the pond? Sometimes this foam can get a little out of control and began to become unsightly.

Foam is the result of an excessive accumulation of organic waste in your pond caused by over population of fish, overfeeding, poor filtration, runoff and various other water quality issues. This foam will mostly occur in agitated water such as around your waterfall. Fortunately, there are a few things you can do to reduce this foam buildup. Some are quick fixes and others are more long-term solutions.

Quick Fix Solutions:

  • Use Shakedown Anti-Foamer – This anti-foamer works quickly to eliminate any foam building. Simply pour it in around foamy areas for immedate, but temporary control.
  • Surface Skimmer – If you have the pleasure of having a skimmer built into your water garden, usually the foam will be pulled right into it.
  • Partial Water Change – Replacing 10-25% of the water every few days until the problem is resolved is one way to dilute the excess organics to help reduce foam.

Long-Term Solutions:

  • Limit the amount of contributing organics by reducing fish feeding and making sure you don’t overload your water garden with fish.
  • Make sure your filtration is adequate for your sized water garden as well as your fish load.
  • Attack and reduce organic build-up an excess waste by using beneficial natural bacterias such as the DefensePAC®.

Hopefully the above suggestions will help you if you are struggling with foam problem.
