What water conditioner do you use?

I am on a well and do not normally use a conditioner. I do have Prime in my fish cabinet (yes, I have an upper kitchen cabinet just for the fish "meds", I have a 3 year old who thinks everything is for him) for emergency spikes or issues.
 
Stresscoat mainly, Amquel+ on occasion. I will compare prices between SC and Prime, and the next time I need some I will probably go with whichever is less expensive.
 
Only Prime............:)

Amquel + (I got a gallon of it )

And Prime if they need some stress coat action
