All systems sell you on why their products are better but at the end of the day its all doing the same thing. Figure out how to maintain your ALK/CA/MG/NO/PO and then when your tank matures and you add sps figure out how to dose trace elements based on your needs. Currently I use red sea color (iron and potasium if needed), Brightwell Strontium and lugols (every 4-6 weeks), and acropower twice per week. It took me awhile to dial in the trace element but with the help of icp tests Its much easier to see if your tank is lacking somewhere. I also have a fuge and cyrptic zone in my sump and dose flourish nitrates to maintain around 3-5PPM nitrates, dosing every 1 month keeps it steady.
To answer your question go with the redsea, its pretty cheap considering you'll be surprise how little you actually need to dose. I wouldnt waste my time with triton who tries to sell you on no water changes but instead your spending a ton on their product when you could go without waterchange aslong as you know your tank is low in metals. Go slow, get the tank bacteria and microfauna going and do a icp test every 3 months. If your going with SPS DO NOT start with 100% dryrock, no matter what you do this is the #1 cause of sps keepers having issues -lack of biodiversity..
