Snowing in my tank

[Sea-nut]

I was using C-Balance and switched to Randy's 2 parts, but now I get snow shower after I add the Alk part .
What am I doing wrong?

Well them look good, what was your Alk and Ca before you dosed? And how much did you dose? What levels were you shooting for? How many gallons of water total volume do you dose for?

You might be seeing a temporary precipitation of magnesium hydroxide, especially if you're using the baked baking soda version. This article has a photo:

Is that the issue?

I agree with Jonathan. Your levels look great. I was freaked out the first time I dosed the alk part of Randy's two part as well. You will see some precipitation in the form of magnesium hydroxide as Jon stated. Totally normal and harmless. Just dose in a high flow area.

Thanks for the help, I am using the baked version also use lime water for top off. total water is 130 gallons and I was dosing with 30ml of C-balance daily and never noticed this before.I am glad it is OK.
Thanks again
