Whats everyone's thoughts on using kalkwasser for alk / cal replacement ? Using kalk also drives up the tanks ph which for me helped greatly. My tanks growth has been greatly improved with the addition of adding more kalk and lowering the workload on my cal reactor. I am dosing on an apex dose 12k MLS of kalk a day...the doser goes one once per hr . This pretty much keeps up with my top off needed .

I just toss a tablespoon in my ato resivor that’s 5 gallons with a very small power head, let it ride. Ato goes directly into a filter sock to avoid making the sump real nasty.
I still hand test parameters and adjust accordingly. Haven’t changed anything in months and test once every two weeks now

I ran several large tanks with saturated kalk for top off for years. Cheap simple and stable. I did start dosing two part on one system that I added a large frag grow out tank to but on a packed 90 gallon reef kalk was all i needed for excellent growth and parameters.

Kalk is fantastic, and I’ve been wondering recently if it’s as dangerous as people say..
I was just thinking about Kalk earlier today and my last tank ran Kalk in the ato, but THEY SAY it doesn’t stay good for very long, I had a 2 gallon reservoir on a 40b and didn’t notice it degrade.
THEY ALSO SAY that you have to premix it and that any slurry can’t get into the tank because it will cause your ph to skyrocket.
However,
I was just watching a video with Vic from WWC and he said they used to mix big batches in a trash can and dump it all in at once with no ill effects, idk the details on the system or how much Kalk they were dumping in but it sounded very haphazard and without the side effects people mention.
I was considering all for reef with this new tank but now I’m not so sure,
I have the 10 gallon reservoir from Red Sea coming to run my ato from and now I’m wondering if I can connect a co2 scrubber to the air inlet on the 10 gallon reservoir to keep 10 gallons of saturated Kalk on hand and to be dosed more or less constantly.
Guess I’m going to toss around some ideas and see what I decide to do.

Nothing but kalk on this tank for 6 years. I never noticed a pH bump but I wasn't trying to raise it. I didn't monitor only tested but pH was always the same as my other tanks that were not getting kalk. I dosed 24/7 with a brs 50ml minute doser on a digital timer. I was at 7200ml fully saturated which was just under my evap rate. I started in my ATO but my evap rate varies a lot so I switched to dosing.
I mixed mine in a brute container. When it was low I would just add 4 gallons of rodi and the kalk powder and mix it in with the batch for a few minutes and let it settle. I kept my dosing tube elevated so it didn't pull from the slurry/sediment. I would clean the brute once every few months or so.
