Agreed, it is also a different type of ionic calcium. If you need to raise ph when raising alk (Part B) use sodium bicarbonate (baking soda) but if you want to raise alk without as much ph increase, use sodium carbonate (soda ash). You can turn baking soda into soda ash by baking it in the oven for an hour to drive some of the C02 out of it. Since Kalkwasser also raises ph, you might consider using the soda ash. Use calcium chloride to increase calcium (Part A). BRS sells the chemicals as a kit. X is also right that a salt mix that has calcium chloride in it already is a option for starting out with higher calcium.

Good news is it's almost impossible to raise calcium to too high levels, it precipitates out. Alkalinity on the other hand can be lethal if it gets too low and it isn't good for it to get too high either.

Good lord there is soo much misinformation out there concerning the topic.

The good news however is that I bought an alkalinity supplement as soon as I set up my tank although I can't remember what its called off the top of my head. Although I dont have anything currently for calcium since Kalk apparently won't cut it.

I guess my next step is a large water change tonight.

So on a suggestion from another aquarist I tested my freshly mixed water and came up with some.. surprising results. I double checked them each with my red sea kit and confirmed with my API kit so they are accurate readings.

Salinity - 1.026
Calcium - 520
Alk - 14dkh
Magnesium - 1640
pH - 8.6

I did however pick up some calcium chloride today form home depot so now I just have to mix them.

Wow what salt mix is that? All those readings are super high...

It's just basic Instant Ocean Sea salt which is why I triple checked it.

Crazy, you must have a bad batch. I use IO salt too and I'm lucky if my alk hits 8, my calcium is usually around 370 and mag at about 1250....

IO is is usally high on, alk and low on calcium. Odd numbers. Buy a different salt mix and alternate them.
