Frequently Asked Questions

General FAQs

Q How deep should my pond be?

A

The minimum recommended pond depth for fish is 18"/45cm, although 30"/76cm is condsidered ideal. Keep in mind that your fish require cool water in the summertime and need to be able to live under the ice in the winter time. In extremely hot or cold climates, a few extra inches in the depth of your pool may have considerable impact on the health of your fish.

Q Are there times when fish should be fed more or less frequently?

A

Yes, there are circumstances that govern how much and how often fish should be fed. In the spring and autumn when temperatures vary from 5-12oC, be sure to feed sparingly, not more than once a day. When fish are first introduced, feed sparingly. During the summer months feeding frequency, especially for koi, can increase to two to four times daily.

Q How do I build a pond?

A

There are many elements and many things to consider when building a new pond - visit our Project page for ideas and tips on how to build the right pond for you.

Q I am trying everywhere to try and get a solution to a serious algae problem in our pond. We have had all three main kinds of algae pretty much all season, although the string algae was a little later getting started.

A

Green water is often the result of excessive organic materials and strong sunlight. Pond water becomes clouded with suspended material such as algae, bacterial blooms, and fine particles that do not settle due to their minute size. Laguna Clear Fast (PT-870) is a quick acting coagulant that bonds with suspended particles, making them heavy enough to be removed by filtration or fall to the bottom of the pond.Indications:Laguna Green Water Clarifier or Laguna Clear Fast (PT-870) may be safely used in any fishpond to quickly correct clouded water by ionically attracting and clumping floating particles. Do not overdose and you should use this product only in conjunction with a filter by removing the foam and placing some poly wool in the filter. After 48 hrs, discard poly wool, replace the foam and do about 30% water change.Your pond should not be in direct sunlight. You should have at least 60-70 % of your pond should be covered in plants; this will help protect your pond from green algae.We would strongly recommend that you test your tap water and your pond water for phosphates. You can bring a sample of each to your local pet store and someone there will help you test. High phosphates can contribute to green water/algae. If you do have high phosphates, we would suggest that you use Laguna Phosphate Control (PT-895) or Laguna Phos X (PT-572) which you place inside of your filter.We also recommend that 25% water change at least every 2 weeks, but be careful if you have high phosphates in the water supply and treat accordingly.We are unsure as to how many fish you have in your pond but the rule of thumb is an inch of fish for every 13 gallons of pond water. Your UV sterilizer is too small for your size pond. We would recommend that you purchase another.We have supplied some link below for you to read. 

Q My pump is not working after re-installing after Winter storage what should I do?

A

You should remove the magnetic impeller out of the pump for cleaning on a regular basis. If it becomes dirty, the impeller can become stuck and prevent the pump from pumping water. Please refer to your instruction manual for details on how to remove the impeller for cleaning. 

Q How can I tell if my UV light is working?

A

If you have a Pressure Flo filter, look for a bluish-purplish glow coming from the indicator on the top of the UVC head. If it is daylight, you may need to cup your hands around the indicator to see the glow.

If you have a UV Sterilizer/Clarifier, there is a green LED light on the head of the unit. If the light is green, your UV is working.

Q I just replaced the UV bulb on my Pressure Flo filter. When I plug in the UV head, the bulb does not light up. Is my bulb defective?

A

It is important that you do not attempt to view the UV bulb when lit. The filter is designed with a safety feature to prevent possible damage to your skin and eyes. To ensure the bulb is lighting up. The UVC head must be installed on the filter lid, and you should look through the indicator on the top to see if it is lit. 

Q Can your products be left outdoors for Winter?

A

Our pumps can be used year-round. If you are going to keep your pump in your pond for the winter, it must be kept running. If you do not plan to use the pump during the winter months, it must be removed from the pond and stored indoors.

In areas where temperatures can drop below freezing at anytime during the winter, all filters, UV sterilizers, ornaments, etc. must be uninstalled, cleaned and stored indoors. Please note that any damage that occurs to these items if left outdoors during winter will not be covered by the warranty.            

Q The LED light on my 500w pond heater fluctuates between red and green. Is this normal?

A

The light is red when the unit is warming up. Once the de-icer reaches its pre-set temperature, the light will switch to green. If the unit needs to heat up again due to a change in water temperature, the red light will come back on.

Q My koi and goldfish love eating trout chow. Their growth rate is amazing. Is it ok to feed exclusively?

A

No, trout chow contains fat levels far in excess of what koi and goldfish require. In fact, the level is so high that fatty deposits will occur and seriously affect the health of your fish. It is normal to see accelerated growth rates when feeding trout chow, but it is not intended for koi or goldfish and will cause long-term problems for both the fish and pond itself.

Q My koi constantly consume the floating roots of my pond plants. Does this mean they are hungry, should I feed more?

A

No, this is a normal activity for koi. An ideal way to protect the roots of your floating plants is by using Laguna Planting Baskets. These convenient baskets will float when not filled with planting media. They are ideal protective cages for floating plants.
