FluidXP, does anyone use it?

At $99 a gallon it SHOULD kicka$$! Does anyone here have any experience with it?

Well, after hunting up a couple of reviews on it I'd have to say that there's no downside to using it, beyond expense. Apparently it does raise reported temps, but only by 1c of so, probably due to its slightly greater viscosity. For now, I'll stick with distilled water/water wetter/algaecide (on account of it being so cheap and all), and consider this stuff after my next flush.
