Pond Salt

Getting the dosage right is what makes pond salt effective rather than wasted, so always measure your pond's volume before treating rather than guessing by eye — our pond volume calculator makes this quick if you're unsure. Most treatments are worked out in grams per litre, so an accurate figure means you avoid under-dosing (which won't tackle the problem) or over-dosing (which can stress fish and plants further). It's also worth checking your pond for salt-sensitive species and plants beforehand, as tolerance varies. Once dosed correctly, many keepers notice fish becoming visibly more settled within days, with improved colour and activity as gill function recovers. A tub kept on hand also means you're ready to act quickly at the first sign of stress.
