Hi,
there are colored tubings, that aren't UV-activ.
And: the clear, UV has only a very slight effect.
If you do add a colored reagent to your water - such as GlowMotion - it won't be visible.
If you do use destilated water and ACFluid so that you do have the natural clear of the water, you will, however, notice a slight blue effect of the tubing. (But its nothing compared to the blue UV-tubing.)
Get the "active blue" tube if you want to have a blue color.
It has a nice shiny blue at day and night.
And the best thing: it lasts very long while the blue UV additives lose their luminosity by and by.
AC does not sell any clear plug & cool tubing which is not UV reactive.
Aha. It's more sort of lit up, than blue. Sort of.
Difficult to describe. That picture should go on the shop site though, I can't be the only person confused.
Anyway, I've just placed my order, I very much appreciate the help you've given me Shoggy. I know you don't work for AquaComputer directly (you're involved somewhere though), but you do a good job for em!
