Turn Off UV Lamps When Doing Any Jobs On Filters

When Doing Some Maintenance Jobs on Filters, Turn Off Any UV Lamps. Often, doing some maintenance jobs on pond filters necessitate some (or all) of the pond’s water to be replaced or “treated”, so it is not necessary to leave any UV lamp turned on. In fact, in most cases, leaving them turned on will only have an adverse effect on the newly-treated water or on the filters themselves. This way, you are also “extending” your UV lamp’s ...


Ripe Fruit Or Onion Smell Coming From Your Pond

Do you notice/perceive a smell of ripe fruit or onions coming from your pond? This is one indication of a “missing link” in the breakdown of common amino acids in your pond’s water. Perhaps when you smell/perceive these indicators, it might be time to consider using a pond skimmer and/or biological filters, particularly those using Zeolite. But of course, before doing so, consult some pond dealers and/or specialty shops and exercise “due ...


Determining Your Pond Water’s Carbon Dioxide (CO2)

Determining Your Pond Water’s Carbon Dioxide (CO2) Contents Based on its Carbonate Hardness (KH) and Degree of Acidity (pH). If there are plenty of plants in your pond, you might want to monitor your pond water’s Carbon Dioxide (CO2) content, because plants need CO2. But CO2 might also be of interest to you because it is intimately related to your pond water’s carbonate hardness (KH) and degree of acidity (pH); dissolved carbonates ...

When Building A Pond, Do Not Expose The Pond Liner To Direct Sunlight

When Building a Pond (or After it Has Been Built), do Not Expose the Pond Liner to Direct Sunlight. Sunlight, specifically its invisible ultraviolet rays, are harmful to your pond’s liner (also called “foil” by some pond owners and constructors), so part of ensuring that you have a good pond edge is by concealing the liner. As a precaution against sunlight (or UV) damage, keep the water level high at all times, especially during the summ ...

The Best Landing Nets Are The Ones That Come From Japan

There’s a saying among pond owners that goes like, “If you want to catch a Japanese Koi fish, always use a Japanese landing net”, and there’s no doubting this saying because the Japanese have been in the Koi-rearing “business” (well, it’s not really a business for some of them; it’s a lifelong passion!) for ages, and they know what there is to know about Koi. Consequently, they have “designed” all their ponds, pumps, filters, ...

Purchase With A “Mindset” For Pond Expansion

When Purchasing some Pumps, Filters, or a UV Lamp/Emitter, it is Better to Buy a Slightly-Oversized One.  Another common mistake among novice pond owners (and even non-beginners at that) is to purchase pumps, filters, UV lamps/emitters, or other pond equipment just “exactly suited” for their current pond’s size. What happens then if you noticed that your Koi fishes got “bigger” and you found a need to increase your pond’s size (or ...

The Best Time To Construct A Pond is In The Autumn

We have stated earlier that it is best to purchase aquatic plants in the Summer or Autumn. It is also best to schedule any pond construction jobs in the Autumn, not just because aquatic plants in pond stores are at their “best” quality in the Autumn, but also because algae do not tend to grow much during this time of the year. ...

Pond Friendly Bacteria Colony Kits

Always Make It a Point to Add “Friendly” Bacteria After Doing “Biological” Filter Maintenance. No matter how careful you are in cleaning your “biological” filters, there will always be a chance that some colonies of the “friendly” bacteria residing in these filters will be lost, maybe perhaps due to the cleaning/rinsing process or because of being “brought out” of the filter. So always make it a point to “replenish” these ...

How To “Open” A Hole On A Fully-frozen Pond

The trick to “opening up” a large hole in a fully-frozen pond is not by repeatedly “pounding” on some area of it (this will only disturb or “stress” the fishes), but by boiling some water in a kettle and “positioning” the kettle itself (NOT pouring its contents) on the area where you want to “open up” a large hole. Keep the kettle on its “position” until it melts a hole. ...

Stay Away From The Sterlet Sturgeon

This is so because the Sterlet (Acipenser ruthenus) variety of Sturgeon fishes has been known to be unsuitable for ponds. Other Sturgeon fish species might thrive in ponds, but the Sterlet, because of its being relatively small compared to its cousins, might not survive in ponds especially if there are other Sturgeon varieties in that pond. ...

What Does “Foaming” Water Indicate? 

“Foaming” on the water is an indicator for the presence of too many proteins, probably attributable to excess fish food and other organic waste. If you frequently see this “foaming” in large numbers around your pond, you might want to consider installing a pond skimmer (also called a protein skimmer) in your pond and/or reduce the amount of fish food given during “mealtime”. ...

Buy Large Pond Baskets With Handles

Buy Large Pond Baskets with Handles for Your Large Aquatic Plants. Since water lilies are best “introduced” to your pond using the “three-depth-levels” method, they can easily “grow” large with as many as 14 long-stemmed leaves “protruding” from each of them. To handle these plants easily, buy large pond baskets with handles both at the “left” and “right” sides, or even at the “top” and “bottom” portions, so that ...

Purchase Air Pumps With Exceeded Requirements

Purchase Air Pumps That Not Only “Match” Your Other Equipment’s Requirements, But Also Exceed them. This advise is very similar to the previous one. Not a lot of pond owners realize it, but when air pumps are “mismatched” or “barely matched” with the other equipment that make use of them (air stones, for example), they prematurely fail, and sometimes it’s not so easy to spot. For example, you might think that your air stone is d ...

Buy Only The Most Delicate/Sensitive Of Water Testers

If you want to be most accurate in measuring your pond water’s chemical contents such as Ammonia, Nitrates, Nitrites, etc., then you’re better off buying those quite-expensive but very sensitive water testers which can detect the presence of even less than 1 mg per liter of these minute chemical substances. Testers which can only detect amounts in excess of 1 mg per liter should be considered worthless. ...

“Moving” Water Will Reduce The Outside Noise

“Moving” Water Breaks the Outside Noise If you happen to live along a busy street or near a highway or a water feature with moving water in the vicinity of your house, the noise from the traffic or the water feature can “penetrate” the ground and/or water of your pond and disturb or “stress” the fishes. To counter these noise, use large pumps or aerators (as well as air stones) that will really agitate (and at the same time, oxygenat ...

When Building A Pond, Make Sure It’s Not Too Wide

There are many benefits of a not-too-wide pond; for instance, it will be easy to “shade” the whole pond (or portions of it) because you won’t have to purchase cloth (or other “shading” material) in unusual dimensions. It will also be easy to “section off” portions of the pond if you would say, want to temporarily “quarantine” some fishes, etc. The list of “benefits” for a not-too-wide pond go on and on.. ...
