Learn what you need for that perfect water garden,


During the winter season:

As you all know winter is now upon us.
Some essentials you may need for the fall/winter season are: the Microbe-Lift Autumn Prep, a pond cover net, cold weather fish food, and last but certainly not least a pond de-icer.

1. A common cause of fish dying is due to improper gas exchange, this happens when the pond gets frozen over.
2. Keep a hole in the ice to allow oxygen to flow normally. NEVER break the ice, such as a hammer, as it could kill your fish.
3. Make sure when you remove your pump for the winter, clean it well and then place it in a bucket of soft water for the winter.
4. Pond de-icers or halogen pond lights will keep the lower level temperatures more comfortable for your fish.
5. Koi need to stop getting fed when the normal daily temperature drops below 50 degrees. But make sure that even when this
temperature drop happens, you need to monitor the pond temperature for the safety of your fish. Koi can survive at a freezing
temperature, but it becomes dangerous for them as well as very stressful.
6. Unlike in the other seasons, during the winter the salt level needs to be higher. For the winter months it should be 0.2-0.3 and this helps to create an extra slime coating. During the other seasons, the salt level should be between 0.15 and 0.8.


A tricky issue for many pond owners is figuring out exactly what pump they need to purchase, but this makes it easier:
1. If you have a pond under 1000 gallons, the rule of thumb is move 2-3 times the water. For example, if your pond is 500 gallons,
you should have a pump that is 1000-1500GPH(Gallons Per Hour).
2. If your pond is 1000 gallons or above, you will need to have 1.5 times or more for your pump. Example, your pond is 1000
gallons, you should have a 1500GPH pump or above.


Another issue many fish owners have is knowing which food to give their fish and when to stop feeding them for the winter.
Temperatures below will be related to water temperature, not the air temperature.
*Over 90 degrees: no feedings are recommended, their metabolism is slowed at this temperature.
*86-90 degrees: 1-2 feedings daily, using Microbe-Lift Cold Weather Formula is good for easier digestion at these temps.
*66-85 degrees: 3-6 small feedings daily. This is the prime temperature for your fish. Using ML Summer Staple, Growth &
Energy, or other supplements are recommended.
*50-65 degrees: 1-2 times weekly, up to once a day. ML Cold Weather Formula is recommended.
*Under 50 degrees: no feedings are recommended because fish will have a very slow metabolism.


As with any pets, you always want to make sure your Koi are healthy, but how can you tell when they are healthy?
Well, first observe their behavior, if they are acting normal, that is a good sign. The normal appearance of a Koi inculdes a
healthy, shiny slime coat, nice healthy looking red gills, no reddish sores, no raised scales, or any issues with their fins. When
winter temperatures seem to be disappearing, temperatures above 50 degrees consistently, your Koi should begin to seem
hungry because their metabolism will be speeding up again. This is the time when they need to be getting fed again.


Many people ask about a good product to help rid their pond of algae, the solution is Algaefix. This is not harmful to the fish, and helps to remove algae.
