I was wondering the same thing. Only thing is that the manufacturers website doesn't mention anything about it including a biocide, but the description on some of the online retailers state that it does. I suppose it wouldn't be much of a bother to just add a few drops of iodine in their just to be safe.
But it is still a HUGE amount cheaper than FluidXP.
My FluidXP seems to have lost a lot of it UV reactivity anyway.
