Magnesium Ratio (2part) when using Kalkwasser AND 2 Part Recipe #2?

[wolfoholic]

You are comparing a hydroxy molecule increase to a carbon tryoxyl, given that, pH Inc ease is going to vary. Ca content is going to vary all the more, and based on the same ratio I believe. Maybe bertoni can elaborate/correct.

Well, I was giving an equivalence only in terms of the amount of calcium and alkalinity added per unit volume. The limewater will in fact raise the pH quite a bit more than either of the two-part solutions. That's why it needs to be added more slowly than the 2-parts can be dosed.

Right. I just wanted to correct my previous post to carbon trioxide, auto correct failed me yet again. (tryoxyde?? )

Now could you calculate the equivalent amount of Kalk per unit volume based on alkalinity OR on calcium. But not both.

 

[bertoni]

The solutions contain carbonate or bicarbonate, not carbon trioxide. There's a difference in the molecular structure.

The solutions each provide calcium or alkalinity, but not both, so we can compute a dose that's equivalent to a gallon of Kalk in terms of both calcium and alkalinity.

Mag Supplementing Recommendations:

Mag sulfate and mag chloride are both important when increasing and/or maintaining your mag level. The mag sulfate will increase your sulfate whereas mag chloride will increase your chloride in your water. The idea is to keep the sulfate and chloride in balance in your water column. This leads to using them in the proper ratio to maintain the proper balance.

Randy calculated the ratios to maintain the proper balance of chloride to sulfate. It will depend on what you are using to maintain your calcium with.

If you are using Calcium chloride (two-part) to maintain your calcium, then use:

5 cups of mag chloride + 3 cups of mag sulfate in a total of one gallon with rodi water. Mix and you can add the particles in the solution.

If you are using kalk water or reactors to maintain your calcium, then use:

7.25 cups mag chloride + .75 cups of mag sulfate.

If you want to bump up your mag level in your tank or you want to increase the mag level in your salt mix or natural seawater, then use:

7.25 cups mag chloride + .75 cups of mag sulfate.

This is perfectly balanced with what is found in sea water and does not take into consideration any additions of chloride from calcium additives.

If you are using reactors (and/or kalk water) and also supplement with calcium chloride, then perhaps a good ratio to use would be:

7 cups mag chloride + 1 cup mag sulfate.

Thanks for the correction. Carbonate it is obviously not carbon trioxide. Two part introduces calcium in a different concentration ratio to alkalinity, when using equal amounts of each, then Kalk, doesn't it? So if you are trying to match the alkalinity brig dosed of 2part to kalk and calcium to kalk you should get two different ratios. Or ami mistaken?

The solutions are designed so that adding equal amounts of each part adds calcium and alkalinity in the exact ratio that Kalk provides them, if we ignore some measurement and contaminant error.

Ha okay. I did not know that.
