Hi all,
cheers Darrel
That should be fine, you shouldn't need to add any more dKH. The rate of dissolution of the cuttle "bone" will depend on how soft the water is, softer water will dissolve the CaCO3 more quickly.I have some cuttle fish in the tank.
I'm not a fan of sodium (Na) addition, I don't think you need to add it, but if you did want an alternative potassium bicarbonate (KHCO3) would be better.I will keep adding the bicarb of soda
cheers Darrel
