Water Treatments 

Water quality is the most important factor in a Koi pond. Koi and other aquatic life can survive in less than ideal conditions however one thing Koi keepers can do to help their fish thrive instead of survive is to make sure that the minerals and trace elements found in natural ponds are in the water in their koi ponds and water gardens.


In almost all cases, the water used to fill our ponds is deficient in most of the minerals and trace elements needed to allow our Koi to reach their maximum potential. What little minerals you have in your pond water are quickly absorbed by the fish, plants, and even the bacteria that colonise your filters. 

Aquasource Balance Enzyme


Enzymes are biological catalysts that speed up chemical reactions in cells.  They perform a number of functions and are vital for life and efficient func-
tioning of the body, including metabolism, digestion and the immune system.

Aqua Balance Enzyme is a complex cocktail of enzymes that are absorbed by the koi via the mucous membranes, replenishing the missing enzymes.  What does Aqua Balance Enzyme do?  Each Sphere can help to convert nutrients into energy, strengthen the immune system, aid digestion and accelerate wound healing.   It can repair enzymes in the digestive system, enabling efficient processing of vitamins and minerals. Poor water quality, medications, stress, infections and genetics can all lead to enzyme damage. Aqua Balance ENZYME can repair and restore the missing enzymes for a healthier koi!


When and How to use Aqua Balance ENZYME


Empty the contents of the tub directly into the pond. One tub treats 4,400 gallons. Repeat dose every 4-8 weeks.
Use after adding medication, increased feeding, adding new koi, rainfall, or any stressful situation. 


Aquasource Balance Remedy

Aqua Balance Remedy is a unique product, formulated with natural ingredients and designed to help your koi thrive. It contains a special blend of Japanese plant & herb extracts, spores, bacteria and a vitamin premix blend.

It is especially effective in accelerating the healing of ulcers, fin rot and fungal diseases and acclimatising new arrivals to your pond.
Water conditions and bacterial pressure are often overlooked when introducing new koi and Aqua Balance Remedy will help ensure your koi settle in to their new home quickly and safely.

Aqua Balance Remedy will also help restore the eco balance in your pond after using chemicals, heavy rainfall or overfeeding.  Also after adding chemicals (including Blanketweed treatments), heavy rainfall, or water quality issues. You cannot overdose.

Linc Fish Health - Envirex

Envirex was created to make ponds far more hygienic and less chance of disease developing in the fish. Envirex degrades all types of solid waste matter whilst lowering ammonia, nitrite, nitrate and phosphate and other unwanted substances in pond water. The product can help to reduce the amount of filter cleaning, pond vacuuming and general maintenance. Envirex is a natural product and cannot kill blanket weed or algae like a chemical but it can inhibit its growth but this requires regular use.

Assessing the dose: All benefits of Envirex are seen with regular use and this is safe as it is non chemical. Customising the dose level to suit individual ponds allows for economic control. The amount required is directly related to the volume of fish stocked and the food they consume not the gallonage and this is why the dose level can be adjusted by the user as ponds vary greatly. If the fish create more waste one week due to heavy feeding use Envirex two or three times that week and then revert to normal use the following week.

Instructions for first use: Envirex should be mixed with water to a milky consistency before introduction into pond or the filter.  When first using Envirex 80 grams per 1,000 gallons to a new pond or 40 grams per 1,000 gallons to a mature pond and wait a few days for settlement. 


Regular applications: After settlement commence weekly use. The average pond with a low stocking density needs 5 grams per 1,000 gallons every 4-7 days to control unwanted substances and solids. However overstocked ponds or those with water quality problems may need 15-20 grams per 1,000 gallons adapt to individual needs.


Envirex is natural and harmless overdose is impossible. The product can be used all year round but if discontinued for winter re-seeds the pond with the first application dose again in spring. There is no need to switch off ultra violet sterilisers when using Envirex and the product does not interfere with any pond medication.

Lincs Fish Health - Pond Detox-PDX

The list of substances that can end up in a pond is endless. In some cases, the fish may be mildly affected by a contaminant whilst the degree of toxicity in other ponds can be severe.


Even at low levels, fish are more susceptible to disease when exposed to any water contaminant. Pond Detox Formula neutralises all forms of pollution, improves water clarity, and settles particles. It can enrich the water improving skin lustre and optimising fish health.


  • Airborne pollution

  • Tap water contamination

  • Heavy metals

  • Horticultural products

  • Plant toxins

  • Acid rain

  • Ammonia

  • Nitrite

  • Chemical overdose and general poor pond water conditions.

When the fish are at greater risk more Pond Detox Formula will be required as a neutralising agent whereas minor irritation following heavy rain for example may respond to less of the product depending on the acidity of the rain.


Pond Detox Formula can also be used in quarantine, hospital, or temporary tank facilities.
