Calcium reactor Redundant solenoid?

[M_norrick]

I am currently running a geo calcium reactor with a ph controller on my 29 gallon reef. I have been having some issues with the solenoid valve leaking by a little from time to time. I have the needle valve choked down to prevent nuking my system and seems to work pretty well but I was thinking about installing another solenoid to help. Does anyone ever run redundant solenoids on their reactors?
