Needed RO guidance inline vs tank

[Dabward]

I haven't grown in almost 6 years. Lots of innovation. Really excited. I'm looking for RO recommendations..

AquaticLife 5-Stage 200 GPD Hydroponic Reverse Osmosis Water Filtration System RO Filter​

6 years ago I had a 3 stage w a small tank and it was a pain.. so I was looking at the above 5 stage And from what I gather. Im better off adding my own minerals like calmag back in after RO instead of getting one of these crazy 11 stage RO filters that add all these mineral back into the water.. hydro will have to wait until the next set of seeds since I'm 12k $ deep.. but I do plan on going hydro.. any input even fake news is welcome.
