Colourless Plant food!

[punka]

Hi guys.

Is there a liqiud plant food that won't discolour the aquarium water?

I've been Using Interpet Flora Boost and it gives my water a brown tinge! Although it does say on the bottle that it "disclolours the water temperaraly"
(LIES!!!! All Lies!!!)
Cheers.

I use Seachem Flourish Excel. It is clear, and does change the colour of that water at all.
