I also called and asked my LFS and they said to keep using the BRS cause the PH would increase and seeing that I don't have a PH testing kit, it would be better to use the soda ash for the time being.

I went on to the @Bulk Reef Supply site and the calculator said to use 71.4 ml. I know that is the amount to bring it up from 5dKH to 9dKH and I wouldn't want to do that in one dose on a 25gallon tank. so in a series of 5 days of dosing I would have to be dosing 14.5 ml per day and that would "theoretically" be increasing the dKH by 1.25 dKH per day.
to me that still sounds like its way too much too fast and I would still have to be worrying about the PH increasing and not having a tester right now. I think my math is on the right track with it, but I also suck at math.
Dosing soda ash (baked baking soda - sodium carbonate) I would definitely be testing for PH increases.

Dosing baking soda (sodium bicarbonate) no worries about PH increase.

I'll get you that answer, one second.
Here you go. Randy explains it better than me:

Here what I've used to adjust alkalinity for decades:

And what I use for alkalinity and calcium in my ATO reservoir top off water, to make kalkwasser:

Calcium hydroxide. Food grade. Cheap and cheap. Can get them at any Wally world....etc.

As @Bleigh stated, assuming your using a refractometer, is it calibrated?

Is your test kits within expiration dates? What kits do you use?

Your alkalinity is low.
Your calcium is okay.
Your mag is okay.
Your N03 is low.
Your P04 is okay.

Nitrate can be raised by feeding more.

Alkalinity can be dosed by using sodium bicarbonate (baking soda, not baking powder). Straight arm and hammer baking soda.

In a one gallon jug, mix 1 1/8 cup of baking soda in with a gallon of RO/DI water. Dose no more than 1dkh per day. 7-8 dkh is ideal. Use this calculator to dose:


Dose slowly into flow, ideally in a sump.

Works everytime.
Do you know what concentration this gets the all too? The calculator tells me I only need 4.5 grams of baking soda to get to my desired alk. Not sure what that translates to with the concentration you suggest. Of course, I could calculate it myself, but I figured I’d see if you knew it off the top of your head.

That answers my questions. :) before I finished asking thank you!!!
Your welcome! Anytime you can save some money and still get the job done, it's a win win!

Just did a little less than third of how much it said would move me up 2.5 dkh. I’ll check the kh once the water has had some time to mix. Dang this has to be an amazing money saver!

I'd be careful raising it more than 1dkh a day!

It works well.

OK, so I looked at that site and I figured that I need 11.4 ml to make the change from 5 to 9dKH. Is that 11.4 ml that the calculator gives out the dose? Or is it the total amount? I’m just confused cause the BRS calculator gave me 71ml total needed for the change....

This is what I got from Randys article. I dont see where the baked baking soda ( a sodium carbonate) will not re dissolve. Maybe im blind. *-}

Many aquarists are familiar with the cloudiness that forms when high pH two-part calcium and alkalinity additive systems are added to marine aquaria.
The initial cloud sinks and spreads out, eventually dissolving.
A similar phenomenon is not observed when adding calcium or magnesium salts, but is observed when adding sodium carbonate solutions. Baked baking soda is sodium carbonate is an alkaline salt
This cloudiness is, at least in part, magnesium hydroxide and is formed when hydroxide ions are added and the local pH rises.
In any case, any magnesium carbonate that does form will probably dissolve later as the pH returns to normal reef aquarium levels, so whether the initial cloudiness contains any magnesium carbonate or not is not a critical issue. It does not contain calcium carbonate if mixed in reasonably quickly (a couple of minutes or less),
as CaCO3 would not dissolve when mixed with seawater (and this material is observed to dissolve).

If using just powder baking soda, not made into solution:

You know about it better than I do.

I know that once it plates heaters and pumps, it doesn't dissolve. Ive had it so thick you needed to chisel it off. That stuff wasn't going anywhere. Maybe it would dissolve in a year or longer......idk.

Have you had it plate everything that generates heat?

@lapin, here's the result of soda ash dosing over 3 months. Precipitation coated everything in my sump, even the tank walls. It was dosed as a drip over hours each time into a high flow area. I just went down to the sump and took these pictures:

I tried scraping it off with a razor blade, three years ago! That's "3" years ago! It's still there. Back then it took muriatic acid to clean my pumps and heaters.

Use the calculator and just select baking soda, enough to raise 1DKH. Dissolve that into a cup or two of RODI water. Pour half of that in the tank, pour the other half a few hours later. Repeat this daily until you get where you want to be. The concentration doesn't matter in this specific application since you just want to pre-dissolve the baking soda to prevent precipitation from too high a concentration for too long in one place.
