Dosing AFR & Kalkwasser

[Ilya_Tihomirov]

No. The calcium and magnesium in the AFR will precipitate as magnesium and calcum hydroxide.

Explain to a person who doesn’t understand much about chemistry, what are the consequences? and when all this gets into the aquarium, should the hydroxides dissolve?

Explain to a person who doesn’t understand much about chemistry, what are the consequences? and when all this gets into the aquarium, should the hydroxides dissolve?

It will instantly precipitate and settle out as white mud.

If you successfully got the solids to the tank, the concerns are the same as dosing a kalkwasser slurry, which include high pH solids landing on delicate organisms before fully dissolving, and initiating precipitation of calcium carbonate, wasting alk and calcium.
