Potassium chloride


Recommended Posts

Hey all,

i need to add more potassium to my planted tank, and ofcourse the best way is thru pottasium chloride or nitrate.

Now i know that potassium chloride is often sold as a salt substitute in supermarkets, but the thing is it also contains other clorides as well. The ones i have found contain ammonium chloride, Now i know this isnt ammonia as such, but i havent researched the reaction of ammonium chloride in water, so thought maybe it could result in ammonia and an acid, which ofcourse wouldnt be good.

So, does anyone know where i can get pure pottasium chloride, or pottasium nitrate as this will also work as well

Thanx Guys.

If you are nitrate deficient, then adding potassium nitrate would be fine, otherwise you are just increasing your nitrates and thats not good for the fish.

I use potassium sulfate, which is available from garden centres and bunnings etc. Its very cheap and effective.
