yeah.. its great eh?...lol
the
kalk is probably the cheapest way, if you have the powder already.
but as Gwen mentioned some use boiling water.
if have a syringe, or something (like the droppers that come with the salifert test kits) you can inject them with the boiling water.
just be careful if you go the
kalk route because the tank is small, and
kalk has a really high
PH. So just make sure you keep an eye on the
PH if you use that method
