R/O, Distilled or De-ionised water (same thing from our viewpoint) is very 
easy to get once you know what to look for! :-)

Ask at any Car Accessory Shop for example, as it's sold for topping up car 
batteries or in super-markets for adding to electric Irons for ironing clothes.
My super-market sells it in 1 Litre bottles next to other car related products.
Your local Fish shop may even sell R/O (Reverse Osmosis) water.

Only if you wish to add Salt to your aquarium.

No idea what a 'mineral pot' is.

We use it instead of tap water as tap water could be high in other chemicals 
like Phosphates and nitrates.
But the amount you'd use in PMDD is negligible in a 50+Litre sized tank.
So unless your tap water is really hard or rich in Chloramines then it's not 
worth the bother I say.

The powder will dissolve slight faster in pure water that's all.
