Water evaporates from a tank but the salt stays behind, so a top up needs fresh water with nothing dissolved in it. The same water is where you start when you mix saltwater, because you control exactly what goes into the mix.
We run Marine Spec from home in Suffolk, so you collect the water from us. Please message before you set off, so we know to expect you.
We sell natural sea water in 25 litres as well. It is collection only too, and you arrange it the same way, on WhatsApp. See both in the water collection.
