Green Pond Care - Natural Solutions To Green Water Pond Problems

When you hear the term “green pond care” your first thought is probably, “yeah, I know all about green ponds”! But do you know why the pond water looks like a green pea soup? The answer is that age old problem called pond algae.

Algae in ponds is nothing new, heck it probably dates back to the stone age or before, but the bottom line is, it can affect any size of pond, from the smallest backyard varieties to the largest of multi-acre lakes. You’ll even find some species of it in the ocean.

The type that you see causing your green water problems though is called Planktonic algae. In a more literal and technical sense, you could be looking at several strains or species of algae in your pond at one time. Do names like Chlamydomonas, Chlorella, Euglena, or Closterium ring a bell? Maybe not, but they are all types of planktonic algae.

You’ll hear a lot of suggestions and comments on how to clear up green water in a pond. Some say that the only way to treat green water is by partially draining or completely cleaning out the pond. Other suggest that mechanical options like ultra violet filtration is the answer. And still others sit confused and helpless, wondering if their fish are still living in the depths of the pond.

To be clear, in many cases, fish don’t have that much of a problem with green water. Afterall it does provide a form of shade in the hot summer months and it most often looks worse than it really is on the health of the pond. Still, no pond owner relishes the thought of looking at it all season long.

So what is the answer to clearing up this green mess? Well there are several and we can talk about a few of them here without making things too complicated.

Out of what was suggested earlier, such as pond cleaning, UV filtration, or sitting helplessly by, all have their merits, except maybe the last one. Pond cleaning is something you’ll want to do from time to time, and usually it’s a great way to start off the spring and get things spiffed up and ready to go. Usually when a cleaning takes place you’re removing some of the organic build up that’s settled through the course of a year and this call help with algae control.

If you have fish, and you’ve taken the steps to clean the pond out, and in a few weeks you see the water turning green again, you can probably blame the fish. Let’s not blame them exactly, they’re only doing what comes naturally, but their waste material may be a problem. As this builds up, nutrient levels rise, and as temperatures warm too, green water may develop.

So if you see this, do one thing. Check your fish load in the pond. Ideally you should have no more than one inch of fish per every ten gallons of water. With Koi fish, it should be one inch of fish per every twenty five gallons of water. Anything more than this and you may be over loaded and will want to think about thinning the fish population down. Your friends can use more fish right?

In terms of mechanical options, ultraviolet filtration is probably the most recommende option for green water issues. Be aware though that this type of filter only works on green water algae and not string algae or other “thick” types of growth. Simply put, if the algae can’t pass through the filter it won’t be affected. Amazingly you might never deduce this by looking at the ads for the devices.

Finally, if you haven’t tried a beneficial bacteria product, consider doing so. These can actually work in limiting all types and kinds of algae because they work to lower the nutrient levels in the pond and they can do so naturally. This makes them much safer to use than chemical options and they can help clean some of the organic material up at the bottom of the pond as well. All in all they represent a very good option to try when confronting a green water problem.

Koi Pond Maintenance - Need For Regular Partial Water Changes0

Koi Pond Maintenance - Need For Regular Partial Water Changes

 Koi Pond with Water Plant

Whether it is a pond or an aquarium, regular water change is recommended. Actually, partial water changes and it should preferably not be more than 50% of the water at a time. This is because fish (Koi included) does not like sudden changes to their living environment. This change could be in terms of temperature, pH and water chemistry.

Firstly, why are water changes necessary? Can I rely on my filtration system to remove fish waste and other debris like uneaten fish food, dead insects and plant matters?

A good filtration system should be able to trap solid debris through mechanical filtration and allows you to remove them easily during regular filter maintenance. However, mechanical filtration is not 100% efficient. Some of this debris will remain and settled at the bottom of your pond and filter. If not removed, they will accumulate over time and pollute the water.

A good filtration system should have a biological filter in addition to the mechanical filter. The bacteria in biological filter should remove dissolved fish waste like ammonia by converting them to nitrite, and then from nitrite to nitrate. This is done through bacteria action in the biological filter is known as the Nitrification Cycle. Ammonia and nitrite are harmful to fish and must be removed as soon as possible. Although nitrate is relatively harmless to fish, excessive nitrate when allowed to build up in the pond can still harm the fish. Excessive nitrate also leads to excessive algae growth which is not a pleasant sight although Koi feeds on algae.

Evaporation of water does not remove nitrates and other dissolved matters in the pond. Regular topping up your pond to replace water lost through evaporation is not considered a partial water change.

Water plants remove nitrates. Even if you have some water plants in your pond, it is unlikely that the plants can remove the nitrates at a sufficient rate compared to the amount of food consumed and waste produced by the Koi. Some advanced Koi keepers have explored the use of commercially designed trickle tower system to remove nitrates. These are quite bulky and not inexpensive. Most Koi keepers will resort to partial water changes to remove nitrates.

Besides removal of nitrates and other pollutants, some Koi keepers believe that regular water changes allow their Koi to grow better and healthier as minerals and trace elements useful for Koi growth are replenished through the added water. Koi tends to perk up and become more active after a partial water change.

How to do a water change? How frequently must it be done?

The aim is to maintain a stable pond environment with good water quality for your Koi. Therefore, frequent and regular small amount of water changes of about 10% are preferred over ad hoc and larger water changes. If your filter design allows you to carry out pond and filter maintenance and water changes easily, then a weekly interval should be sufficient. You may want to flush the bottom drains or perform other maintenance of your filter system while carrying out your partial water change.

Even with regular water changes, you should monitor the nitrate levels in your pond. Nitrate cause a slight brownish tint to your pond water. Other symptom of excessive nitrates is excessive algae growth! The most accurate way is to measure nitrate and water quality using a water test kit. Commercially available water test kits allow you to measure parameters like pH, nitrite, nitrate and oxygen levels.  Nitrate level should be less than 25 mg/litre. Ad hoc water change is still needed if the water quality if not up to the mark.

Water that is removed will have to be replaced. If you are refilling your pond with tap water from the utility company, you will have to consider the additives to the water. The tap water contains chlorine to kill germs and it is also a fish killer. The chlorine will dissipate from the water naturally after a few hours. Depending on the water you are getting from the utility company, you could potentially do small percentage (less than 20%) of water change without using dechlorinator and not kill your fish. If you have an option to increase aeration to your pond like turning on a fountain or venturi pipes, you should do it. Aeration helps remove chlorine. Refilling the pond through a spray hose helps provides aeration and dissipation of the chlorine from the water as well. If you have to perform larger amount of water change, a dechlorinator to remove chlorine is strongly recommended. In any case, it is better be safe than be sorry.

Koi Pond Maintenance - Basic Care0

Koi Pond Maintenance - Basic Care

 Koi Pond

A koi pond is a very entertaining and soothing garden fixture that many home owners like to have. Although it may seem that having one requires a lot of work, the actual work is the maintenance and care of the fish pond and not building it. The actual work is also not as much as large scale work as long as the relative size of the backyard pond is correct and meets the requirements for the fish to live comfortably and in fine health.


Filtration is one of the most necessary things for a your pond to be able to support the fish and other forms of life in it. The filter acts as a cleaner for both the water and the pond in general to help keep the water clean and livable. There are so many different kinds of filters available that one should consult a professional koi dealer in order to be able to choose the right filter to fit the size and depth of the pond as well as considering the number of fish in the koi pond. The mechanical filtration system of the pond filter will help to keep other harmful organism in check so that the desirable living things such as the fish can live longer in a stress free environment with no competition for air and food. The filtration system also maintains that clarity of the water, while some even help to keep algae growth in check.

Certain types of beneficial bacteria can also help to filter the debris and dirt in a koi fish pond. These bacteria break down the accumulated debris and dirt on the bottom of the pond to help with the filtration.

Scheduled Review and Cleaning

Always remember that the key to koi pond maintenance is to regularly monitor the pond, and set up a regular cleaning schedule.
