Go the CuCl route, it only grows, nothing to throw
away. Mine's residing in a 2,5 liter tank ATM but is
getting a bit dense so I'll transfer it to something
larger along with a bit of water. If it does get too
much anyway just evaporate the excess and keep the
crystals until you find a way of getting rid of them.
