What would you do - Auto Top Off

I am down to two options for intalling an auto top-off system to my sump tank. So here they are:
Option 1:
I would "T" the line going to the reservoir (trashcan) and use float/solenoid system to auto top off the return section of my sump tank. I will be using the system described in this thread:

I like this because it is truly automatic meaning there is no separate tank/bucket to fill and then drip into the sump.
Option 2:
Rig up the "T" line from the RO to fill my Kent Doser that will constantly drip into the sump. Or simply just refill the Kent Doser daily or every other day. I might be using this to dose Kalkwasser into my reef but I am still unsure whether Kalk is the best way to go. Otherwise, I will be using B-Ionic to maintain calcium levels. I really prefer using the float system in option 1 due to it being totally automatic and I think it will be able to more accurately maintain salinity.
I am open to others Ideas so shoot!
