Yes, I agree. It's not Kalk.

1/8 tsp to 100 mL rodi,
then 5mL/25g, correct?

Doesn't particularly matter. Just an estimate will do the job?

I'm not sure exact amounts mater to much like jedimasterben mentioned.

I used this recommendation someone gave me and marked off that water bottle I posted earlier just to maintain consistency.

Quote:
230 ml RODI and 20 ml calcium crbonate. Mix it up but it won't disolve. Add 1 ml per 20 gal of the solution you just made

Add 18tbs CaCO3 then add RODI to the 900ml line.
Thanks. Are you dosing daily or weekly?

Mike

I was dosing daily and then weekly. Never noticed a difference on water clarity. However, I have noticed an increase of coraline. Which they may like the textured covered surfaces that the CaCO3 sticks to. It was something that was also proposed as what people notice when they dose a product like purple up as it also contains CaCO3.

Fwiw 1/8tsp per 100mL doesn't cut it imo. When I dosed it was barely cloudy. I remember dosing coral snow and the tank being pretty cloudy. So I doubled it to 1/4tsp per 100mL rodi and its better. I think 1/2tsp per 100mL might be a good to make it similar to what kz Coral snow looks like.

How often do you dose?

My first time dosing this was yesterday, today my water was the clearest it's been since I started this tank over 6 months ago. For now I'm going to dose it 2-3 times a week.

Does anyone have a picture or video they can link to show how "cloudy" the water is supposed to look immediately after dosing?
Are there any possible negative effects from this?

Thanks.

It just looks like someone stirred up a ton of super fine sand. No negatives except a cloudy tank for a couple of hours.

Sorry to resurrect an old thread but anyone still dosing calcium carbonate?

I just ordered a 5lb bag off Amazon and can't wait to try it out

I still use it once a week or so. Visible difference the next morning. A 5 lb bag is going to last a lifetime.

Yeah it was $11 with shipping for 1lb or $13 for 5lb with free shipping

Wait - just in case I misread - is there an argument that fine chalk could actually be used by coralline incorporating it into its matrix?

Could it be a vehicle for collecting dissolved organics, not for export through a skimmer, but for assimilation by living organisms? Kind of like a shopping cart of yummies where the cart ends up being used to build too...

Basically, particulates can reduce light penetration. So coalescing then into a larger "food particle" improves light penetration for photosynthesis, and calcification while simultaneously providing a meal...

I realize that calcification needs free Calcium ions most of the time, but could fine powder Calcium carbonate be "assimilated" rather than synthesized occasionally?

No one explicitly said this- but looking at its action as a flocculant, the increase in coralline, the water clarity... I'm just connecting dots.

Finely ground calcium carbonate seems to act as a flocculant. It might tend to remove a fair amount of calcium and alkalinity from the water by acting as a source of nucleation sites. I don't think it'd add any to the water. Even as a very fine powder, not much can dissolve, since most tanks already are in supersaturation.

I wasn't talking about adding calcium to the water... not dissolving.

I was looking at the calcium powder collecting dissolved organics and making a food source that 1. allows more light 2. collects food for corals to consume 3. provides small calcium carbonate particles for assimilation (not synthesis)

I'm not sure how many corals would consume such particles, and I don't know whether their digestive systems do much with the calcium carbonate. It might work as far as the organics providing food.

I am presuming FM coral balance is very similar but with some form of nutrition added...

I looked at the description of Coral Balance, and it's hard to tell much from it. The product seems to be something like a carbon source along with other trace elements, but I can't be sure.

I have used it for months, I will add some vinegar To it and see what happens.

It fizzed a little but ( FM coral balance) there was plenty of precipitate left in the vinegar so it must contain a percentage of ca,chum carbonate but there is defo other stuff in it.

Well, I'm not sure why they would put calcium carbonate in Coral Balance, but you're probably right about that.
