I am looking to possibly switching from my current 2 part system, BRS soda ash, calcium with added Tropic Marina A and K. I have around 120g total water volume to my system and dose around 100ml of both daily. I usually mix up around 4 gallons at a time in a bucket of each solution to dose to the tank. I was hoping to find a way to dose kalk to the tank in a similar way if possible, mix a 5gal bucket worth and dose from there, is that possible? Would I need a small pump to keep the kalk mixed? How much kalk is added to 1g of RO water? Is there any trace elements that can be mixed directly with the kalk to supplement the tank? Is there a way to calculate how much kalk I would need to dose daily from my current set up? TIA for all the help!

My Tank Thread
5 gallons of kalk in such a system would only last a couple of days. You’d dose roughly 40 times as much as the two part.
Maybe look into AFR as an AIO additive? I can't say it's better but it's easy. I love it because it's so easy to use and corals do very well.
I buy it in powder form and mix it. I think it may be a bit more expensive than other methods but I'm willing to pay extra for ease of use.
This tank has been on AFR for two years. Corals were all little frags when added. I have it on a doser but manual dosing is fine as well because the alk is slow to be released.

Wow awesome tank! I will consider making the switch, any ideas if it 1 for 1 with 2 part as far as how much to dose? I use a DOS and trident controlled dosing currently.I buy it in powder form and mix it. I think it may be a bit more expensive than other methods but I'm willing to pay extra for ease of use.

I'm going from memory so hopefully @Randy Holmes-Farley will fact check me but I seem to remember that ESV 2 part provides 1.7 times more alk then ESV 2 part. Please verify this tho. I used a calculator for ESV then did the math because I couldn't find a calculator for AFR at the time.
EDIT: i may be wrong but I'm pretty sure auto dosing is not recommended with AFR because it releases alk over a period of time not instantly. I usually wait 24 - 48 before testing when I'm making adjustments to the amount being dosed.

I have switched from 2 parts to AFR and loving how easy it is, tho im only running a 20 gal, but its such a concentrated solution, the same bucket size last me at least twice amount of the time and theres only one bucket i need to refill. (A bottle of TM element A&K would last for more than 2 years so i dont count them lolll). I also buy the powder form and mix it myself.
Afr will cost a fortune. Add some kalk into your ATO. Maybe .5 ts per gallon at first and then work up from there. You will still use the 2 part, but reduced a ton.
I dose full strength kalk in my ATO and then add 30- 45 ml of each part per day. I also add A and K into my 2 part. System volume is around 150 gallons. Around 8 gallons per week in evap.
