Baking soda dosing in nano

[Patrick.S]

I run Kalk in my 10 gallon and after a few testing issues my kh is a tad lower than I want it at 7.3. The kalk seem to be sufficient to maintain the levels, but not to raise them. I figured I would use baking soda to gradually bring my kh up to 8.5. The problem I'm having is knowing how to properly dilute the baking soda for so small a water volume. The reef calculator says I need 1 gram of soda to raise my dkh up to where i need it. Should I mix it with 1 cup of rodi and then dribble it in over the course of a couple days? Dilute it more? For reference, I think my actual water volume is closer to 8 gallons after displacement. Thanks!

You'll forgive me, but I have to ask. Why don't you just use more kalk?

The soda will increase the alk unbalanced to the calcium.

My understanding is that Kalk reaches full saturation at 2tsp per gallon. I'm up around there and it's not going up. More kalk would't dissolve.

If you make saturated kalk, limwasser , in rodi in a seperate container , add that to the Ato.

Then increase the amount of that saturated limwaser you use.

I use a 500 ml container to measure. So if 100 ml in the 2.5 gal ato resivor dissent work. Next time I add 200ml of saturated limewasser. Etc etc.

This insures the max saturation at all times and makes dosing slightly more precise.

You can dissolve the baking soda in a cup of water and add it in a few doses. Dribbling isn't needed.

If the op were to use saturated limwasser , how much would he have to add directly to the tank?

400 mL of saturated limewater will boost 10 gallons by about 1.2 dKH.

Thanks for the info all!!
