Glenn recommends you use his Salt Mix recipe, which is included in the calculator. After that, you test for the major elements (ALK, CA, MG, No3, Po4 etc) once the system is running for a bit. You will not have to dose No3, Po4, right away as it is a new system. Most likely you will have to dose carbon and Po4 remover (FE+) as the system matures. The calculator is built based on his recipes and products, so if you don't have those you will have to make your own. Personally, I just bought several of his products with the exception of Soda Ash, Ca Cholride, MG Sulphate etc that can be sourced domestically from BRS.
I'll give you and example of how I use the calculator:
No3:
On the above line, I measured 0 No3 one particular day. My target value is 2.5 ppm. For my Tank volume (250 liters) I have to dose 4.50 ML to raise the target value to 2.5 ppm.
Po4:
In the line above, I measured Po4 at .024 My target is .04. I need to dose UP TO 1.87 ML daily in a (250 liter) system. *Note* this is a max daily dose as dosing liquid iron can be hard on fish. You have to build up to this dosage to get your fish used to the high dosage of Iron. You measure Po4 weekly to get the value down to your target, in my case .08. Again, this calculator is based on Glenn's products. Others on this board have made their own liquid Po4 remover but as I stated I opted for Glenn's method.
For other elements, Sr, K, Boron, I use ICP tests every 3 months to balance out. The testing for those elements is not frequent and I found it easier to use ICP to balance instead of running my own tests. I've found Sr in particular to be a pain.
I dose Iodine based on the calculator, I do not test for it as it rapidly depletes. I take the maximum dose for my system and drop it in. Calculator:
The above indicates maximum measured (peak) value. The maximum dosage I can use is .20 ML daily on my system. Indicated on this table included in the calculator:
It was a bit trial and error in my experience. I use Glenn's calculator for things like:
Po4, No3 control
Other element control (K, B, Sr,Iodine)
I don't use his calculator for:
Alk, CA, MG, Carbon.
The big three are easy to test and manage, we all try to keep those stable (Alk). For Carbon I use Vinegar, and through trial and error dose to properly manage No3.
Hope this helps,
Tom
Just wondering how one plans for this with any of these systems. I'll have to do some more reading on this system which isn't a bad thing. Maybe it is easy to incorporate especially if soft and lps corals are fine.
Looks promising though
