Can I add Sodium Bicarbonate to auto top off? "HELP"

[Arruna]

Hello!

I have a 150gal Saltwater tank that has been up for about 3 years. I recently started adding corals in addition to my fish.

I recently checked my levels now that the corals (one tube coral, a rather large frog spawn, and a calm) have settled.

PH: 8.2
Calcium: 350
DKH: 5
Phos: 0 or at least to low for the API kit to detect
Nitrate: 0 or at least to low for the API kit to detect
Nitrite: 0 or at least to low for the API kit to detect
Ammonia: 0 or at least to low for the API kit to detect

So obviously I need to get my DKH up. I have a large garbage can holding RO water as my auto top off. Would adding Sodium Bicarbonate to this so that my tank it gets doses slowly over the day everyday be a good way to raise my DKH permanently?

Or any other advise would be great on how to higher my DKH and Calcium long term would be great.

In ATO, kalkwasser

Kalk would be better to get your calcium up too. Need to raise nutrients as you raise dkh as well

And I can put that in my ATO with no issues? (as long as I dose it to how much is in the tub of course?)

Thank you both! I just dont want to crash my tank!

Just make sure that you clean your ATO pump regularly with citric acid or muratic acid. Do not use vinegar, there have been problems with the acetate from the vinegar splitting plastic pump bodies.

I recommend using an actual doser, rather than adding kalk to your ATO.

it can clog your ATO pump, causing issues. Your tanks evaporation rate can also vary, which would affect how much you are dosing.

Kamora X1 dosing pump for $50 and call it a day.

When I was using it I started off with 1/2 teaspoon per gallon and had no issues with the pump. Keep the pump 1/2" off the tank bottom to avoid the slurry. Pump will clog overtime so like many others I started using a doser to go off for 4 or so seconds every couple hours (10G tank) and additional top off with my fresh water ATO.
