1. To achieve (raise or maintain) calcium level in tank, is it better to use Kalkwasser or those Hydro Calcium Premium by Aquaz for example?

2. I read that for Kalkwasser to be effective, purified water must be used instead of tap water and dosing is the best method. Why using tap water to mix the Kalkwasser powder is 'asking for trouble' as stated in some articles?

3. If we don't use purified water for Kalkwasser, is it as good as we don't use Kalkwasser but choose addictives like the Hydro Calcium Premium where it is more convenient?

4. If one will to use Kalkwasser, is it still required to use the Aquaz Hydro Calcium Premium? Or we can onli choose one to use?

5. Comparing both products, which is more effective in raising or maintaining Calcium?

Thank you.

Do you know how much you lose first?... before you try to maintain. Why Ca only?

clean water is best as it increases the solubility of kalk, which leads to a great deal of wastage as the kalk can't dissolve nicely.

Kalk and Ca are totally different minerals, the former increase both your carbonates and Ca in balance, while the other Ca only.

If your raising Ca alone then use Ca additives only. But up to a point, you'll need to use both(ca and alk)... as you never lose Ca by itself.

Thanks Madmac. Now you mentioned 'clean water', is that the same as purified water or another type again??? :P
