| Child override What is daylight? Daylight (or white light) is made up of a series of colours, collectively referred to as a spectrum. This is known because when a beam of white light is passed through a glass prism; the white light splits into seven visible colours with red shades at one end through to blues and violets at the other. Filters block colours When a white light source has a coloured filter placed over the beam the observer will then see the light as a colour, i.e. a green filter shows as green – blue as blue, etc. It is useful to realize that when white light hits the filter, the other colours are being blocked. The filter is allowing only certain colours of the spectrum through. Parklink-Blue blocks the red end of the spectrum By adding Parklink-Blue to water, a filter is being created to block colours from the red end of the spectrum getting through to the bottom of your pond or lake. Photosynthesis needs red light By adding a filter to the pond or lake water you are blocking some, or all, of the red light and the process of photosynthesis is interrupted. |
| Child override 1 x 100g dye sachet will treat 1,000,000 litres of water. Calculate the volume of water in the pond: |
| Child override Wear gloves when handling. Do not open the sachet or touch the powder. Place the soluble sachet in the middle of the pond and let it dissolve. Maintenance Top Ups: A general starting guide is 10-50% of the original dose each month. Parklink-Blue Dye Powder Sachets By supplying Parklink-Blue dye powder in separate water-soluble sachets it is easy to calculate the number required to dose a lake or pond. In large lakes, if a boat is being used, simply drop sachets in different areas where they will dissolve releasing the blue dye. By spreading the area, the time taken for Parklink-Blue dye to fully mix with the water is reduced. If a boat is unavailable face the water with a breeze coming from behind. Drop a few sachets along the edge and throw the others into the water. The breeze will move the water and the blue powder dye will dissolve and mix in quite freely. Parklink-Blue will fully mix with all of the water using this method but may take a little longer. Parklink-Blue Dye Liquid If a boat is being used, gently pour the amount required into a wide area. The blue liquid dye rapidly disperses and will fully mix with all the water in the lake. If a boat is not available pour the desired amount into the water near the bank. To speed up the distribution it is preferable to use the banks of the lake that have a breeze flowing towards the middle. Regardless of which method is used, the water will look to have more colour in the first few days because it takes a little longer to mix from the top to the bottom. |

| Child override Frequently asked questions about pond dyes The list of Parklink dye FAQs is forever growing as we add our answers to your questions to help the decision making of our customer’s future purchases. If your question is not below please ask away. We are happy to assist and we will add your question(s) about pond dyes to this list. Will Parklink pond dyes work in all ponds and lakes? Our pond dyes will create a light filter in all waters. The minimum doses do require at least 1 metre of overall depth, anything less requires more to compensate, for example, a pond at half a metre will need a double dose. 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. I have fish in my pond, will they be safe? The dosage recommended is very low and has no effect on fish. The European regulations have a fish test that uses the dyes in concentrations 1000 times greater than our suggested dose without any harmful effects. My pet drinks from our pond, will it be ok? Dogs, cats, rabbits… We have been asked this question many times and there appears to be many exotic ‘pets’ as well as the more popular ones. Water treated with Parklink pond dye will not be any different to the way it was before being added, so, if the pets were OK before, they will remain that way. Our pond is visited by frogs/newts/Insects/invertebrates/dogs/cats/rabbits/insects – will the treated water be safe for them to drink? The actual dye content in the water is very low and will not be harmful. Please note that a well known brand of energy drink has 65 times more dye per litre than a litre of pond water dosed at the minimum rate! What happens if we put too much pond dye in our water? The water will be a deeper shade, and possibly opaque. Over time, rainfall will dilute the colour to the point where it will all be gone. It can also be diluted by adding more water. If emptying the pond is required, the water should be flushed into soil beds – please avoid letting over dyed water get into surface drains or streams. Any water getting into a stream or drain will not be harmful, but anyone seeing coloured water flowing by may report this “pollution” to the authorities for investigation. Does the pond dye 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 recommended dilution rates no staining will occur. Parklink-Reflect uses a higher concentration of dye and may result in slight discolouration of surrounding stones and water features. Spillages of the dye on surrounding areas should be washed with copious amounts of water first and strong sunlight should fade any residue. Is it safe to swim in water treated with Parklink pond dyes? Yes. All Parklink Pond products are made using European Food Approved Colours, but give the concentrated dye time to mix into the water before diving in! Can we use more than the recommended dose? Parklink-Blue can be overdosed by many hundreds of times. It is sometimes necessary to add more than the minimum dosage. I have seen photographs where Parklink-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, even the reflection of a blue sky can make the water look bluer than it actually is. It is almost impossible to capture just how pale the water is once coloured. How long does it take for Parklink pond dye 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 more movement of the water, the quicker the pond dye will mix. If re-circulating pumps are used, the mixing will take less time. Will Parklink dye damage water pumps? No. The dye is completely soluble and will pass through pumps and filters very easily. Can Parklink dye be used with other chemicals? Parklink-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 Parklink dye? 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, Parklink dye has a long shelf life. |

Tony Boulton –
This powdered dye is awesome! Much more concentrated and works much better than other dyes I’ve used in the past. Fast delivery also.
Kate Rowntree –
I’ve only just started using the blue dye, having initially used the black variety. It works well, but is very messy and you do need gloves. You apparently can just toss the bag in, according to the instructions, but I like to pour it around the places I most want to shut out photosynthesis. It works well in preventing ongoing algal growth.
Andrew Trolove –
I have a 1000m3 pond just outside my house that is ornamental as well as an irrigation storage pond (lined and the previous owner had koura in it – I don’t). Over the last 2 years have cleaned out yearly and chlorinated 3 times a year plus circulated water all with limited success in keeping water clean and limiting smell.
This summer I have used the blue dye for 5 months (and the bio REGEN-Sediment product) ie added it each month plus carried on circulating the water.
The water, although is blue, has no algae visible, looks good, and does not impact on our irrigation or the colour of our dog.
Will definitely be using it all year round as very happy with the water clarity, no algae, and visual look just outside our window – thanks Hayden for your help.
