Just been recharging a sachet of Purigen and saw this thread,
We buy Asda own brand Thick Bleach, just 39p a bottle, which states 4.5% hypochlorite.
As Purigen say use an 8% solution at 1:1 then surely just use Asda bleach virtually neat ?
However after doing that for 24 hours, twice, as @Wookii
mentions the beads are still a very pale brown / creamy colour, nothing like the almost white colour when new.
So is it worth buying that quiet expensive 14% hypochlorite solution to get it virtually white ? or just reuse as is and expect a slight reducing in efficiency ?
Did read comment about the Freshwater section instructions and using an extra Buffer was really just a total belt and bracers thing and not normally needed .
