Nah it's not if ur going to do the triton method u have to dose all four equally as over time as your tank matures it will all balance out it's not like dosing this to get alk number then doseing that to get ur calcium number
U dose all four evenly and worry about alk staying at 8 I have no idea what my magnesium is and I don't really care either my calcium was 490 three weeks ago but I do know and the only thing I care about is my alk has been 8 everyday plus or minus .2
So if ur going to do this forget about everything else but alk. Keep it at 8 and dose 1 2 3a and 3b the same.
I don't know what 4-5 ml of carbonate is so I can't help ya there but if you tell me how much dkh u lose a day I will be able to tell ya how much to start out at well close enough to what u should start out at.
It's a simple way to do reef keepin don't overthink it and try to adjust because something is higher then what u want as it will all even out. Plus triton elements are good in that they will not raise it any higher then a set point so you can't really over dose. What you want is when your done bottle 1 that bottle 2 3a 3b will also be done.
Trust me the people that get in trouble are the people that try to deviate away from this very simple method except d2mini I don't know what happened with his tank and it's a shame. I just think he didn't have the right refugium to get it started for the triton method and he should have started out with the other methods.
