Calcium and alk supplement?

Malifry97 · Oct 20, 2019

Ok so I recently got seachem calcium dosing mix and am using baking soda for alk. Whenever I combined them in my gallon jug I waited a few minutes and tested. My alk and calcium were perfect! They were at 400 and 9. How is this possible? Why didn’t they both just precipitate out? Hey I’ve been dosing with it and it’s kept my tank steady so I know it didn’t precipitate out. How is this possible?

Anyone?

I’m not sure what you are asking. You mixed the two additives in the aquarium, or outside it? What is perfect? The aquarium water, or the additive mix?

If you mixed them outside the tank, they will precipitate and those numbers are very low for an additive.

I mixed them outside the tank. It hasn’t precipitated and I’m using as my top off

What would be the ideal numbers for the calcium and alk additives? I have two large sections of organ pipe coral in a 36 bow front. How much of the alk and calcium supplement should I add?

If they are precipitating out I don’t know how my tank levels are remaining constantly at 9 alk and 400 calciumwhen I am using the additive for top off. I’m confused.

you made it way to diluted to be useful. As I said in the other thread, start by reading some basic dosing articles.

there is no ideal, but there are many recipes. Thousands of dKH and tens of thousands of ppm calcium are the right range.
