It says the ingredients are calcium acetate, and magnesium acetate, and hydroxide salts.

Hows this work as a single dose? Seems good that you wont worry about increasing sodium and sulphate.

Id like to diy this and dose it, but im worried that acetate will lower ph too much. True?

 

[Randy Holmes-Farley]

Salifert has a similar product (they were first I think, years ago).

Calcium acetate only lowers pH when the acetate is converted into CO2 and OH-. So the effect is like adding some vodka, not like adding vinegar.

The two possible concerns with this approach are cost and whether you want as much organic carbon dosing as it provides based on your alk and calcium needs.

 

[Cory]

Ah ok. Is it supplying calcium and alklainity in the right proportions that calcification uses?

Im not too worried about bacteria my tank has low demand. Might be good for the sponge and corals.

I can buy calcium acetate for 50$ at 500g. I wonder how long that would last?

 

[Randy Holmes-Farley]

Ah ok. Is it supplying calcium and alklainity in the right proportions that calcification uses?

It could be. I can't tell exactly what ratio of calcium to magnesium they use, and they exact ratio depends on the tank, but the alk to calcium plus magnesium is right for calcification.

In terms of effectiveness, 500 grams of calcium acetate = 335 grams sodium carbonate + 465 g calcium chloride dihydrate

 

[Cory]

Lol so for 50$ im basically getting a box of baking soda that costs 2$?

Is this the rich mans dosing supplent?

Could i make my own at home with vinegar and calcium chloride?

As Randy alluded to, be careful dosing vinegar (or vodka or sugar) since it's a carbon source. Using it on a tank with low nutrients or using too much too quickly could have significant effects.

For example in my 75g calcium consumption is 2.8gr Ca per day, if Calcium acetate is used this will add organic carbon equivalent to 200 ml 5% vinegar or 25ml vodka, which is very high dose for my 75 gal.

That's a great example!

FWIW, I get 165 mL of 5% vinegar for that amount of calcium and if I round that to 200 mL, Jim Welch won't like it.

 

[Cory]

So calcium acetate products are a poor choice for sps tanks?

Can we make calcium acetate at home?

What sort of oxygen depletion are we looking at for 165ml?

Yes I put a little bit more vinegar (or vodka) to the salad I'm afraid.

It is a concern for high demand tanks. 165 mL of vinegar will consume more than 8 grams of O2 to fully oxidize, which is about what is present in 1200 L (320 gallons) of seawater. If course, it does not all oxidize instantly, but it is a big demand.

It is not easy to DIY. I tried with vinegar and calcium carbonate. Got a volcano.

I found this:


He did the same as you. But he says you can also use calcium hydroxide. Hows that work?

 

[Cory]

Isnt that making a little calcium acetate when you put vinegar into limewater?

 

[Randy Holmes-Farley]

Isnt that making a little calcium acetate when you put vinegar into limewater?

Yes. That is what I did when I was dosing vinegar saturated with calcium hydroxide.

 

[Cory]

If i put 500 grams of calcium hudroxide with the same of vinegar how much calcium acetate will i get? Or whats the good way?

 

[Randy Holmes-Farley]

To make calcium acetate (dissolved in water) from 500 grams of calcium hydroxide, you''ll need to add it to 8 liters of vinegar (5% acidity).

I wouldn't store that solution as bacteria may grow in it. If you add excess calcium hydroxide you can raise the pH to prevent growth. I'd add it until no more dissolves, then the pH will be high enough to prevent bacteria.

 

[Cory]

Thanks Randy!

Thats going to be lots of calcium acetate?

I'll definitely add more CA(OH)2 to prevent bacteria.

500g calcium hydroxide costs me 15$. And 8liters of vinegar will cost about 6$. So 21$ to make how much calcium acetate, 500 grams?

And to be sure, ill add 500g of calcium hydroxide to a big container, like a 5 gallon bucket, then ill slowly add 8 liters of vinegar. Correct?

Is the vinegar making the water durring the reaction, or do i have to add it?

Safety, any harmful gasses released? Should i wear a full face chemical breathing mask? (I got one)

When I made this for vinegar dosing, I added the calcium hydroxide to straight vinegar. No need for further dilution.

Vinegar is 95% water.

 

[Cory]

Ok so ill put 8 liters in a bucket then spoon in 500g calcium hydroxide.

But please tell me if its 500g calcium acetate after the water is evaporated.

No, it will be more than that. More like 1067 grams, plus any extra calcium hydroxide present.
