7. Clear water binds particles floating in your pond water together so when they pass through the filter because they are bigger they stay there, within hours to days your pond water will be crystal clear. Clean the filter after the pond water has cleared. Clear Water is safe for fish & plants in the correct dose.

8. Algae Killer kills the free floating algae spores in you pond water, within a week you pond water will be crystal clear, even if the pond water was like pea soup. Algae killer will not remove the algae that grows on the floor or sides of the pond, that is part of the natural environment and provides microscopic food for the inhabitants of the pond. Clean the filter after the algae is gone and the water is clear. Algae Killer is safe for fish & plants in the correct dose. 

    If algae is a constant problem, you may need to put up a shade sail or Buy one of our UV lights, this is a permanent solution to Algae problems, as the water passes through the UV sleeve, the ultraviolet light kills the algae spores. This means no more algae. You do need to replace the UV Light tubes yearly.

9. In winter much of your good bacteria dies, and this makes the environment in the pond become unstable, This can result in sick fish, susceptible to diseases & parasites to prevent this use a pond block till spring.

    Pond block release a constant supply of good bacteria, which eliminates the build up of deadly toxins and acid water.

10. Salt the pond, salt naturally builds up body slime on fish and gives them protection against bacterial infections. Dose 1kg of pool salt to every 2000 ltrs of pond water. Pour in where the filter return water is, straight from the measuring container. Do this once a year every Autumn.

 200g block treats up to 1000ltrs , 1 kilo block treats up to 50,000ltrs

 Feeding your koi & goldfish from Autumn to Winter

koi or goldfish in your pond, are poikilothermic, “cold-blooded.” Their internal temperature varies with the ambient external temperature. So in the wintertime when your pond’s water cools, the body temperatures of your fish cool, too. And with that dip in body temperature comes a reduced need for nutrients.

Our wheat germ-based diet is designed to transition your pond fish from eating a high-protein, high-energy diet, to fuel their active underwater lifestyles – to their winter period of metabolic inactivity.

The Wheat germ we sell, is high in carbohydrate-based nutrients, packed with natural vegetable proteins and designed to provide your pond fish with the immune-system boosting vitamins and minerals to get them through the winter.

Wheat germ requires less energy to digest, so its perfect to ease the fish into or out of the colder months.

1kg, 3kg & 6kg Wheat germ

Time to Switch!

start transitioning your pond fish to the wheat germ-based diet in Autumn, when the water temperature starts to cool, feed your fish a mixture of the wheat germ & the normal food you feed, gradually increasing the wheat germ and decreasing your other food until you’re feeding 100 percent of the wheat germ food.

Where ever you live in Australia Wheat germ can be added without causing any harm to the fish ready for the inevitable drop in temperature.

Only start to feed the koi and goldfish a higher protein pellet again when the weather turns warmer again, add a little of the protein to the wheat germ as the water temperature goes up.

 Do I need a UV Steriliser for my pond?

If you want to have a natural looking pond with a lot of plants and just a few smaller fish, which will go greenish in summer you don't need a UV!!!

Or go bog garden, filter your pond in a smaller pond first with lots and lots of plants in it, plants can help to clear the green colour by using up the nutrients that would go to the algae... They're literally starving the algae.

This can work with goldfish , but koi fanatics like us like to have lots of fish, their beautiful and you want to be able to see them, this is when a UV is better than any other method of keeping the pond crystal clear.

A backyard pond depends on good, or beneficial, bacteria to balance the water and process nutrients and waste products, but bad, or harmful, bacteria thrive in the same conditions and can take over a pond. A UV filter, which uses light wavelengths to destroy bacteria, can prevent the bad guys from taking over without destroying all the good bacteria your pond needs to thrive

A UV provides 100% success for achieving clear water from single cell algae in water. While a UV will provide clear water it does not filter the water. ... You need the biological filter to break down the ammonia given off by the fish and to break down dead organics including the dead algae that is killed by the UV.

At Windsor Fish Hatchery we also use UV units on our ponds so we can keep an eye on the health of our koi & goldfish, so being able to see them clearly when feeding is very important.

There is a guide to the size you will need for your pond on our product page. UV sterilizer units and replacement lamps.  UV units
