Concentrations of additives

[Halostemanic]

I’m sure this information is available but I can’t find it. I’m looking to find out how much dKH my tank is using per day based on a stable Alk and set dosing.
I maintain my reef at 8.1 dKH by dosing 20mls of each core 7 other methods.
Is there a table available that gives the value for example 1ml of 3a in 100 Litres raises alk by X?
In fact are the values available for all 4 bottles so I could work out Ca & Mg too?

Thanks in advance.

I've been wondering the same thing. I haven't been able to find any detailed info.

I have never found this info and have read several threads on this subject.

Seems like a secret, but in the end I dont know that it matters.

Every system will be different, and even if theis factor is known
It would not be accurate for that system.

So stating 20ml will raise your Dkh in a 100g system by 1.0 in a labratory I doubt would honestly equate the same result in 30 tanks out in the real world.

Its just a puzzle that we must figure out.

In my tank 240 total water volume with my coral load I dose 26ml over 24 hours to stay at a 8.5 Dkh. For me the non specific person that I am, that works for me.

Yeah I agree it’s a nice to know instead of a necessity but I am interested to know how much major trace elements my tank is consuming per day. Wouldn’t it interest you to know that your tank consumes 1, 2 or 3 dKh per day or 30ppm of calcium?

This is exactly the same for every tank irrespective of volume. The only variable is the uptake based on your corals, lighting, reefing method etc.

Yes.
But if your/my tank drops a full DKH in a 24 hour period lets say, 8 to 7

Then you increase the ALK dosage by 5ml and it goes back up to 8 then you would know that 5ml of solution would be close to 1 DKH.

That's a big swing in a 24 hour time frame and just using it as an example.

Now as far as the trace elements go that's a whole different thing.

I’m looking for the concentrations so that I don’t have to Turn off the doser and allow my dKH to drop to find out.
Plus there are other factors that will affect dKH uptake. It can’t be that hard to find the values I’m looking for... surely.
