Frequently Asked Questions

Are Dyofix products safe?

Yes. All of the dyes we use comply with the European Food Additive regulations, the dosage recommended is very low and has no effect on fish, any visiting wildlife or domestic animals. The product has been tested at a rate 200 times more than our recommendation.

Do Dyofix products help to reduce weed growth as well as algae?

Yes. Rooted weeds at the bottom of the pond require sun light to grow in exactly the same way as algae. Weeds that have leaves at, or above the surface of the water will be able to benefit from the sun light, so it is recommended that Dyofix should be applied in early Spring before the weeds start to grow. Prevention is always better than a cure!

The weeds in our lake are growing, is it too late to use DyoFix?

We have people contact us when really bad pond weed problems are already present and after treating the water with Dyofix have reported significant progress and improvement - some have noticed this overnight others after a few days.

Do your products need to be licensed by any authorities?

NO, Before they were banned, chemical remedies, collectively known as Biocides (algaecides, herbicides etc) did require approval in the UK by the Health & Safety Executive under "The Biocidal Products Directive (98/8/EC)" which is implemented in Great Britain by the "Biocidal Products Regulations (BPR)", "The Control of Pesticides Regulations (COPR)" or "The Plant Protection Products (PPP) legislation". From 18th March 2010 these products had to be withdrawn from the market throughout Europe.

Does the product stain?

In concentrated form, dyes WILL stain hands and clothing, so it is always recommended that gloves should be worn when handling the products. At a recommended dilution rates no staining will occur.

Is it safe to swim in water treated with Dyofix?

Yes. All Dyofix Pond products are made using European Food Approved Colours.

Can we use more than the recommended dose?

Yes. Dyofix can be overdosed by many hundreds of times. It is sometimes necessary to add more than the minimum dosage, for example, if the weeds have grown and are getting near to the surface, this is normally 2, 3 or 4 times the minimum, but it depends on just how close to the surface the weeds are. There are a few lake owners that want to enhance the look of their lakes and, as with Kew Gardens in 2013, they used 10 times the minimum dose.

I have seen photographs where the Blue has been used and this made the water look very blue, why is that?

There can be many reasons, photographs taken as the pond is being dosed, owners deliberately over dosing for effect for example. It is almost impossible to capture just how pale the water is once coloured.

How deep in shade will the water be once the product has been applied?

The illustration here shows that the minimum dose is almost imperceptible. Please note that the colours shown are indicative and are not intended to be taken as accurate.

Will Dyofix work in all ponds against all weeds?

Almost. The depth of the ponds must be a minimum of 1 metre for it to be most effective against the majority of rooted weeds - there is no maximum depth limitation. It is possible for the product to work in shallower waters, but higher concentrations are required.

How long will it last?

There is no definitive answer to this question as strong sunlight and rainfall both have an effect on the dye. The Sun will fade the dye and rainfall will dilute it. We suggest that a monthly top up of 10 to 15% of the original dose should be made in order to keep the dye concentration at its best.

How long does it take for Dyofix to mix into a pond?

This depends on a number of factors. The size of the pond - with a very big pond, it may be difficult to reach the middle (without using a boat). The "stillness" of the water - the more movement of the water, the quicker the dye will mix. If re-circulating pumps are used the mixing will take less time. The simple movement of fish helps to distribute the Dyofix.

Will the Dyofix damage water pumps?

No. The dye is completely soluble and will pass through pumps and filters very easily.

Can Dyofix be used with other products?

Dyofix Pond Blue can be used with other chemicals provided that they are not Chlorine based. Chlorine will attack the dye by bleaching it and rendering it useless.

What do I do with unused Dyofix?

Keep it in a cool, dry place with the lid firmly in place and use it for "topping up" or the following years(s). Stored in this way, Dyofix has a long shelf life.
