I'm impressed at the increase I had in coraline when switching to the Salifert ALl-in-one.
I'll be honest that I don't test half as much as I should, but seeing the difference as soon as I started up the Salifert brand, wow - I was blown away.
It's worth giving each a shot for a few weeks (salifert, C-Balance, Purple Up/Liquid Reactor) and see what works best for you - trial and error is what this is all about!
