Soda ash liquid supplement for alk

[N11morales]

So I recently wanted to try dosing soda ash to supplement alkalinity.

I made my soda ash by baking baking soda

I was wanting to use this on a dosing unit.

Tank is 280G
Alk 8.0
Usually keep my alk at 8.5.
I know it’s going to raise my ph also. My ph is low so I’m fine with the added bonus.
How much liquid would I need to dose to get Alk up by .5 dkh


Do I mix 1/2 cup or 1 cup of soda ash for 1 gallon container?

Ty I could only find a calculator that showed how many grams of soda ash to add.


So add 1 cup of soda ash per 1 gallon of rodi?

2 cups or ~375 grams per 1 gallon RODI.

2 cups or ~375 grams per 1 gallon RODI.

So 2 cups and brs sight says to dose 200ml of liquid soda ash to move from 8.0 to 8.5 in my system.

If that's what the calculator states, I would go slow and space it out to get a baseline and start understanding your Alk demand over a week. Dumping 200mL of Alk all at once may shock your tank.

Here is a hypothetical that is on the BRS website:

Example for 100-gallon aquarium:

Alkalinity Level Day 1 @ 8pm - 9.0 dKH (desired level)
Alkalinity Level Day 5 @ 8pm - 7.5 dKH (current level)
5-Day Alkalinity Requirement - 107.1 mL (provided by BRS Reef Calculator)
Daily Alkalinity Requirement - 21.42 mL (107.1 mL / 5 days)
