Best trace elements to dose? Any 1 bottle wonders?!

[LesPoissons]

Hi all,
My tank is 5 years old now, Im pretty much done adding things and just letting it grow. Its on dosing pumps for ca/alk, no pox, and an auto top off ect. After not testing or doing water changes for 5 weeks (usually on a 2 week rigid schedule!) due to travel and life- my tank does not appear to need a water change so Im trying to move away from them as much as i can. (Its 250G- water changes are a PITA). I was wondering- what trace elements do you use to dose? I have the red sea ABCD kit but I would need 4 additional dosing pumps to get away from manual dosing. Is there a "1 and done" type of bottle anyone likes or should I stick with the ABCD.

If it were that simple, then they would have stuffed everything into one bottle. Tropic marin split into two bottles.

On my 120 no scheduled water changes from day one.
I did one around 12 months, 9 gal, just because and one at 14 months, 12 gal, after a fluconazole treatment for hair algae.
I have run DSR ez trace from day one. Currently running 6ml a day.
This keeps mag, iodine, and k at desired levels. It has other trace elements too. I only test for those elements every few months.
I dose esv strontium once a week to maintain 8-10.
My carx runs manmade media so only replaces alk and ca.
Just started low dose of ez carbon which is vinegar, sugar, and iron blend, also a DSR productd.
Only 3ml a day as this is a strong carbon dosing product.
I am not using it to control anything just to feed the corals and im sure it helps keep no3 low as I run <10.
It does make my skimmate pretty nasty.

I dose Coral Essentials Black Label day and night. I’m not sure what would happened if I stopped, so I keep dosing because everything looks so good. Acropower has helped my SPS.
