Please be SERIOUSLY careful about how much Fast Fibre you feed.
I have no idea why Allen & Page continue to market it as being suitable as a total hay replacer, when this is clearly not the case:
It contains 0.88mg/kg of selenium, so if fed as a total hay replacer, this would be 10kg for a 500kg horse, so a total of 8.8mg selenium in the diet per day. This is way above what NRC considers a safe upper limit (they say no more than 5mg a day under any circumstances).
If you are feeding 4kg of it, that's nearly 4mg of selenium from the Fast Fibre alone, and that's before you take in account whatever's in your hay/grass and before you take in account whatever's in the Pink Powder vits/mins that you are feeding.
Selenium toxicity is not somewhere that anyone would want to go.
