well I dont follow what you want to know.
If you mix alot of kalk with saltwater you will have snowstorm, a precipetaion event as the calcuim and alkalinity fall out of supersaturation.
Agreed, and worse...on top of that, if you are dripping salt water into your tank constantly to make up for evaporation, you'll be raising your salinity...it won't take long before you are at a dangerous salinity level. When water evaporates out of the tank. it's mainly just water...the minerals and compounds remain, so your salinity rises...that's why you top off with fresh water. If you were adding salt water as top off, your salinity will rise even further...
I guess I should explain a little better. I want to use saltwater from my sump to add into the Kalk reactor instead of freshwater top off. Will it work the same as freshwater?
I would still think you'd have potential imbalance problems...out of curiousity, why do you want to use salt water from the sump instead of fresh water?
My freshwater top off (float valve) is already mounted in the sump. I don't have enough room to incorporate another "bucket + valve" resevoir to use for the Kalk reactor.
Man I dont know how saltwater, with CA, and Alk already dissolved into it would take becoming a concentrated kalk solution, I think it would cause all kinds of problems as little particles start to form, and then become bigger particles all inside the reactor. I think fresh ro water is the way to go.
From what I gathered, I guess mixing with saltwater won't work. I didn't know what the outcome would be that's why I asked. Thanks for everyone's inputs, I will figure some other way to dose it with freshwater.
