WHAT IS NUALGI PONDS?Nualgi is a liquid additive containing 12 essential nutrients on a nano silica base to restore balance, improve water quality, and control nuisance algae in your pond. Nano silica is both a nutrient and a carrier that prevents the nutrients from reacting with each other.
Unlike traditional additives, Nualgi’s nano scale (measuring 5-100 nm) nutrients remain suspended for longer duration, disperse easily across the water column and are therefore “bio-available” to marine organisms.
HOW DOES IT WORK?
WHAT ARE THE BENEFITS?Nualgi Ponds has been developed specifically to starve nuisance algae, reduce foul odors, and increase oxygen levels in your pond. Nualgi promotes greater fish and plant health while keeping the water crystal clear. Enjoy your new habitat and show off your pond as your fish become more active and your plants gain more color.

Directions For Use:
Nualgi is dosed at 1ml per 1000 gallons per week in ponds with algae. If possible, Nualgi should be dosed early in the morning.
Adding extra will actually reduce the effectiveness. It is better to do half a dose than to overdose
For ponds under 5000 gallons with good flow, Nualgi can be dosed directly into the skimmer or the waterfall or some other area of good flow. For larger ponds, dilute the dosage in a jar of pond water and pour it in the accessible parts of the pond by walking around the periphery.

Regular, partial water changes help to improve water quality by flushing out dissolved waste materials and replenishing essential minerals.
Adding LED Pond Lighting is great way to extend the time you can enjoy your pond. Lighting up waterfalls or fountains adds a whole new dimension to your pond at night.
Lotus make stunning pond plants. The larger varieties have huge leaves that grow up to 24” in diameter held up to 3 feet above the water. Their flowers are very fragrant and measure up to 8” in diameter. There are also medium and dwarf sized lotus that will suit any size pond or water feature.
Yes, water lettuce do actually flower! However, the flowers are so small most people never actually notice them.
Chagoi are single coloured koi that range from light greenish brown to dark brown. Although they don’t have bright colours or intricate patterns, they are well known for growing larger than other varieties. They are also renowned for being very friendly and docile and are usually the first koi to come and eat food from your hand.
Oxy-Pond Cleaners are a great product for spot treating string algae on waterfalls and in shallow streams. Simply turn off your pump, sprinkle it on any algae, wait about 15 minutes and turn your pump back on.
Great Blue Herons are typically solitary birds, so placing a lifelike heron decoy at eh edge of your pond often deters them from visiting your pond and eating your fish. If you have a heron that lives near your pond, moving your decoy around from time helps to maintain illusion.
Goldfish make ideal pets for small ponds because of their modest size. They typically grow 8”- 10" long, although they can occasionally get bigger. The best types of goldfish for outdoor ponds are Comets, Sarasa Goldfish and Shubunkins.
Having some algae in your pond isn’t a bad thing. In fact, algae consumes nutrients and waste products and helps to purify your pond water. Many small zooplankton feed on algae which then become food for small fish.
While Tropical Water Lilies may be a bit expensive and will not survive the winter in the pond except in very warm climates, they are definitely worth it. They bloom profusely all summer long; they are available in many colours and they often have large exquisitely patterned leaves.
Floating plants like water lettuce and water hyacinths provide shelter and hiding places for koi and goldfish and can protect them from predators like herons.
Frogs typically hibernate during the winter by burrowing in the mud found in ponds and lakes. Their metabolism slows down enough that they can absorb all the oxygen they need through their skin.

Body flukes (Gyrodactylus sp.) are a fairly common parasite found on pond fish. They do not lay eggs like gill flukes, instead they produce live young. They are found both on the gills and the body of fish.
Covering 50%-65% of your pond’s surface with plants is recommended to help shade the pond and keep the water cool in the summer months. Plants also consume excess nutrients from the water reducing algae growth and help to maintain optimal water quality. These 'Clear Water Plants' are some of the best plants for maintaining a clear, healthy pond.
If you plan to keep koi in your pond, it should be at least 4’ deep to give them enough space to swim and develop properly.
