About Blagdon Green Away – 1000ml
Green Away (1000ml) is a Blagdon-branded liquid pond treatment marketed to clear green water (suspended algae) and to assist mechanical filtration. The manufacturer product page lists the bottle identity, product code (2674) and family sizes, and states claims such as “Rapidly clears green water”, “Enhances mechanical filtration” and “Naturally safe.” Blagdon’s site does not publish a static litres-per-bottle coverage or a fixed dosing table on the product page; instead the company directs users to its interactive Treatment Dosage Calculator to compute the correct dose for a specific pond volume. Manufacturer guidance found on Blagdon’s support pages includes an effectiveness pH window (6.5–8.5), a recommendation to administer the treatment in the morning, and advice to treat the entire pond rather than only parts of it. The site also provides a simple verification test (adding two drops of Green Away to a glass of pond water to watch for sedimentation and clearer water). The product page shows the product barcode and a placeholder weight value but does not provide a downloadable Safety Data Sheet (SDS) or technical datasheet for this exact product on the same domain. Because Blagdon relies on an interactive dosing tool, this record does not state any pond-capacity-per-bottle figures, nor any electrical/flow/UV/cable specifications (not applicable to a liquid chemical and not provided by the manufacturer). If a litres-per-bottle coverage is required, Blagdon’s Treatment Dosage Calculator (on the manufacturer site) is the manufacturer-authoritative source to compute doses for specific pond volumes.
Best for
Clearing green (suspended) algae in ponds where pond pH is between 6.5 and 8.5; manufacturer also states it enhances mechanical filtration.
Things to consider
Manufacturer product page does not publish any litres-per-bottle coverage or fixed dosing table; Blagdon directs users to an interactive Treatment Dosage Calculator for dose amounts. No Safety Data Sheet (SDS) or downloadable technical datasheet for Green Away was found on the manufacturer domain during this review. Numerical fields such as pond capacities, flow, power, UV wattage and cable length are not applicable or not provided by the manufacturer and are therefore not stated here.
Installation
Manufacturer recommends treating the entire pond and administering Green Away in the morning. Use Blagdon's online Treatment Dosage Calculator on the manufacturer site to determine the correct product dose for your pond volume. The manufacturer also suggests a small verification test: add two drops of Green Away to a glass of pond water and observe for sedimentation and clearer water after a few hours.
Maintenance
Manufacturer guidance indicates that if the initial dose only partially clears the water, a repeat dose the following day may be recommended (as per Blagdon support/FAQ pages). Follow doses calculated by the manufacturer’s Treatment Dosage Calculator.
Safety
The product page includes the marketing claim “Naturally safe.” No Safety Data Sheet (SDS) or downloadable technical datasheet for this exact product was located on the manufacturer site in the searched pages.
