GH Plus is a completely natural and biodegradable additive that incorporates calcium chloride to establish the ideal mineral balance in your pond ecosystem. This product plays a crucial role in facilitating CO² transport, promoting healthy plant growth, and binding harmful substances, thereby preventing acidification of the water. The general hardness (GH) value of a pond serves as an indicator of the concentration of essential minerals, such as calcium and magnesium, that are dissolved in the water. To accurately assess your pond's GH value, you can utilise our water test kit, which is available for purchase separately. Ideally, the GH value for a pond should fall within the range of 8 to 12°. If you find that the GH value is below 8°, GH Plus can effectively raise it quickly without causing any cloudiness in the water, ensuring a clear and healthy environment for aquatic life.

How does it work?
The average water hardness or GH value must be between 8-12. This value indicates how many minerals, including calcium and magnesium, are dissolved in the water. These minerals are necessary for CO² transport, the binding of harmful substances to prevent acidification of the pond water and are essential for the growth of all aquatic plants.
The use of Moerings GH Plus increases the water hardness. If there is a strong deviation from the ideal value, most of the natural processes in your pond cannot take place. The plants extract minerals and rainfall reduces the GH value.
It is therefore important to use Moerings GH Plus regularly. Moerings GH Plus is a pure and natural top product. Food-proof products are used for this purpose. These products have excellent performance and maintain the values well.

Instructions - dosage
25 ml (1 measuring cup) increases 900 litres of pond water by 1 GH. This is an indicative value. In case of high PH and or KH values or strong contamination of the water, the increase may be less. It is important to measure this properly.
1 litre provides an increase of 4 GH for 8,000 litres of water 
2,5 litres provides an increase of 4 GH for 20,000 litres of water 
5 litres provides an increase of 4 GH for 40,000 litres of water 
10 litres provides an increase of 4 GH for 80,000 litres of water

Is it safe?
Moerings GH Plus is completely biodegradable and safe for humans and animals.

Live Plants

Suttons strives to ensure that all its plants are delivered to you in the perfect condition for planting. While the majority of our nursery plants cope well with slight delays in intransit, sadly, the time it takes to deliver to certain locations in the UK means that we can't guarantee this for some of our smaller plug products and tender bedding and vegetable lines, which do not respond well to the extra journey time. So regretfully while we offer the majority of our live plant offering nationwide, we are unable to ship plugs, begging plants and tender vegetable plants to the following areas: HS, IV41-IV49, IV51, IV55-56, KW15-KW17, PA34, PA41-48, PA60-PA78, PA80, PH40-PH44, TR21-TR24, ZE1-ZE3.

Non Standard Deliveries

We are committed to finding a way that we can resume or normal services again as soon as possible. Please accept our apologies for any inconvience caused.

We reserve the right to revise any carriage charges in the event of carrier price increase or other unforeseen circumstances. We will always advise of the carriage charge before payment is taken.
