b-ionic or kalk

for a 30 gallon system with a 14 gall sump what would be better,doze kalk out of the ato or manually doze b-ionic . I ask since the system is not that big and is not going to be so overloaded with corals maybe I don't have to doze on a daily basis what does the forum think right now I doze maybe twice a week and it stays level at 420ppm of course only have muchrooms and a torch coral for now, planning on getting a soft coral or polyp this weekend. I need advice

a good 2 part supplement is better in the long run because it will contain the proper amount of magnesium and other trace/minor elements in the calcium portion. Kalk does not contain magnesium.

Both are perfectly fine ways to go.

I choose to use limewater for my system, and I just give a little magnesium boost in my water change water. With some brands that would not be needed as they have a lot already.

You can do a DIY two part for a lot less than B-ionic, but B-ionic is a fine product.

There's nothing else one could or should add into limewater. Just add the solid calcium hydroxide into the fresh water and stir to dissolve, let it settle and you are good to go.

Sbazain, just to clarify: Kalk = Calcium Hydroxide, and Kalk + RO/DI = Limewater


In case there was confusion.

Well, just to expand a bit,

Kalkwasser is a german word that refers to calcium hydroxide (or calcium oxide) dissolved in fresh water.

Limewater is the english word for that same thing. In english, lime is calcium hydroxide and quicklime is calcium oxide.

The term "kalk" on Reef Central is used variously to mean the solid calcium hydroxide, or just a short nickname for kalkwasser.

was only attempting to clear up any confusion on the terminology being use, not trying to show anyone up

No worries. I didn't think you were. I just didn't want people to think that if someone on RC said "dose kalk" that it meant calcium, rather than limewater/kalkwasser/calcium hydroxide solution.
