BRS Kalkwasser worth it

I've seen BRS Kalkwasser. Seems pretty cool. Is it worth getting the starter kit? I so, do you suggest dosing my RO or setting up a drip. This is all new to me. 120g tank with only a cleanup crew thus far. Fish next. Then someday coral.

If you don't have coral you likely don't need it at all.

As potatohead said, without corals you don't need it. When it comes time to start dosing, then Kalk is a fine choice. You don't need to use the BRS stuff. If you can find it in the grocery store or online, pickling like is the same stuff.

So until I start filling the tank with coral, don't bother?

With that in mind, how important are my calcium levels in a FOWLR tank (before I put any coral).

The calcium level is important to coralline algae, as well as stony corals and clams. If you don't want to grow any of those organisms in your tank, it doesn't much matter what the level is, as far as we can tell.

Maintaining NSW levels are fine for a fish only tank and will aid in stability of PH, alkalinity and magnesium, which keeps fish healthy. Calcium depletion is only a concern when you have coral and inverts. I use Pickling lime (calcium hydroxide) in my ATO top off to supplement my calcium.

Using the following calculator: http://reef.diesyst.com/chemcalc/chemcalc.html

It's food grade. A lot of us use it. Cheap too. Walmart and others carry it in the canning section of the store.

Lime contains calcium hydroxide (or oxide), and provides calcium and alkalinity at the approximate ratio in which corals consume them:

What he said. I have 1 small LPS and a zoa frag and a small chalice frag in my tank with 2 nems. I move slow. Yet my 90 gallon total needs about a half gallon of saturated kalk to keep dkh stable. The coralline algae and all the crap on the rock need it.

I drip for the time being. I have used BRS stuff. There are cheaper options out there but not at the size your probably wanting to buy.

I could get by with 2 part, and still dose it. but the kalk helps my pH. It's cheaper for my needs than 2 part, and it's 1 bottle in the place of two.

The price difference between the BRS kalk and Mrs wages is negligible . They are both calcium hydroxide.

Thanks for the info. I wouldn't know where to begin with the pickle juice versus using kalk at a predetermined level.

I used Mrs Wages lime for many years. Not available in my small town. Bought a jug of BRS kalk a few months ago, I don't see any difference. BRS kalk is $12/gallon, a gallon of dry kalk weighs what, maybe 3 lbs? Mrs Wages is available on Amazon, 6x 1lb packs for $23... It's a wash, to me. I like the BRS screw top jugs better than Mrs Wages packaging.

From a dosing point of view, I don't think there's any difference at all.

They all should be about the same except for impurities. Exposure to air will cause the lime to convert back to calcium carbonate over time, but other than that, it is stable and should last a long time if kept sealed. A food-grade product should be fine. I might worry about an industrial grade product.
