## Description

From the manufacturer Usage concentration See table below for recommended dosage levels Tonic 0.1% Ph Buffer 0.1% Anti-Stress 0.3% Supportive 0.9% Add gradually over 3-4 days Once added it will remain indefinitely, only being removed by water changes, and water outflow such as through-flowing stream. When the Pond Guardian Tonic Salt is removed in a water change, the volume of replacement water must be treated at the original dosage rate to return the whole pond to the desired salt concentration. Also, however, if at some stage the treatment is repeated to combat another problem, remember to take account of the original dose when calculating the dew dosage level. Pond Guardian assists the pond owner in safeguarding against fish disease It can be used in a variety of ways As a general pond tonic. A dose of Pond Guardian will help your fishes' immune system to combat disease. See the table below for recommended dosage levels. As a mild pH buffer. Guards against potentially damaging swings in pH (excess alkalinity or acidity), helping to keep the pH stable at an ideal level for pond fish - close to neutral. To help minimise the effects of stress on pond fish . Pond fish are often subject to stress. This can be caused by a number of factors, the most common being over-crowding and poor water quality. Stress makes fish more susceptible to disease and can therefore be a killer. As a supportive measure when treating for disease. When treating certain diseases, such as Ulcers Fropsy, Fungus, etc. with pond water treatments it is often recommended to support the treatment with a course of pond tonic salt.

Review: Recommended. - I can recommend this product as I have used it before. One of my fish was displaying swimbladder problems so I added Pond Guardian Tonic Salt to the pond and left it in for a week before diluting it. The fish appears to have recovered and is swimming around quite happily with no issues.

### ⭐⭐⭐⭐ Unclear instructions
*by A***S on 13 October 2025*

Unsure about how to use this product, it says on the pack that to add gradually over 3-4 days and this level of salt should only be maintained for a maximum of two weeks, beyond two weeks it can cause plant damage. So does this mean I need to empty the pond and put clean water in so it doesn’t kill my plants? 2 fish dead this morning after putting only a quarter of the pack in, the pond is 2,500 litres. Not happy at all
