Your saying to vary the dosage of all 4 of the base elements for a change in the dKh? So, for example, your dKh is at 6.5, but your Ca and Mg are spot on your target, you increase even the Ca and Mg even though they were correct? I'm a little confused
There are quite a few scenarios that you can encounter when dialing in your dosage and a few different approaches you can take to make adjustments. I didn't get too specific into each scenario and it's correction as it would have made for quite a long video and is something I will plan to break down in future how-to videos, but for the scenario you mention, you could just mix up some Alkalinity Increaser and dose it to your tank to target a rise in alkalinity.
Here's a few other scenarios that I'll clarify a bit more down the road.
It is important to note also that most of these are rare but easily fixed and usually only happen during the early stages.
Scenario 1
Alk Low
Ca Low
Mg Low
Solution - Raise all equally
Scenario 2
Alk High
Ca High
Mg High
Solution - Lower all equally
Scenario 3
Alk Ok
Ca Ok
Mg Ok
Solution - Maintain dose
Scenario 4
Alk Low
Ca Ok
Mg Ok
Solution - Maintain dose, dose additional TRITON CO3 liquid buffer/NaHCO DIY Salts to raise Alk then maintain
Scenario 5
Alk Ok
Ca Low
Mg Ok
Solution - Maintain dose, dose additional TRITON Calcium liquid buffer/CaCl2 DIY Salts to raise Ca then maintain
Scenario 6
Alk Ok
Ca Ok
Mg Low
Solution - Maintain dose, dose additional TRITON Magnesium liquid buffer/MgCl2 DIY Salts to raise Mg then maintain
Scenario 7
Alk Ok
Ca High
Mg Ok
Solution - Maintain dose on channels 1/3a/3b reduce dose of channel 2 until Calcium level drops to required amount.
Scenario 8
Alk Ok
Ca Ok
Mg High
Solution - Maintain dose, water change to reduce elevated Magnesium levels. (Only if Mg very high)
Scenario 9
Alk Ok
Ca High
Mg High
Solution - Check KH test for accuracy, reduce dose of all solutions, set KH to 7 and retest.
