Where do you get your bleach and what make, manufacturer?
Has anyone in the UK been able to get 8.25% Hyprchlorite Thin Househol Bleach?
Thank you.

Asda sell thin bleach which I've been using for a while now. Think I've used a morrisons one too. Thin bleach and no added perfumes.
Cleans up lily pipes and regenerates purigen no problem

I use regular Clorox (available in the UK) bleach - don't use the so-called splash-less bleach as it is thicker and less potent. Mix 1 part bleach with 2 parts tap water in a bucket and let it sit for 24 hours - I stir it up a couple of times, if I remember to do so. After that I rinse the Purigen and fill the bucket with regular tap and a capful of Prime and let that sit for another 24 hours and its ready for reuse. I usually re-use it 2-3 times... others 4-5 times.

Cheers,
Michael

"Clorox (available in the UK)" This is the problem. It isn't available in the UK.

Don't use purigen myself and no idea how important a sodium hypochlorite content of 8.25% is but if you're adamant you want that percentage you could always buy some sodium hypochlorite 14% and dilute it. I'm assuming that would work? Hopefully somebody with a more chemical knowledge will chime in if I'm talking out of my posterior.

Personally I'd just use regular bleach like the others mention.

I'm looking forward finding a method better than mine.
I am using the Morrison thin bleach. Asda's one will be the next, but I don't expect better results.
I'm using it undiluted, in 2-3 sessions of 24 hours. When the purigen is starting to look good enough, I will rinse it same way as the others.
I use two bags, one in the filter and one in a plastic box full with water (don't let it dry).

Maybe Milton steriliser solution would do it if thin bleach as seems the case is unavailable

When I used to use Purigen I never found I got adequate whitening of the resin with standard thin supermarket bleach which is typically only 1% sodium hypochlorite.

I bought 14% sodium hypochlorite, as @John q suggested, from APC Pure, and it produced a much better result for me.

my household bleach is 5%. I find that by bleaching purigen before it turns too brown, you can more easily return it to the 'close to new' colour.

I think the 1% is a UK thing. The US has stronger household bleach also.

In this instance does whiter actually mean it has been restored better though?

I use Purigen and just use a 2/1 water/ bleach solution to restore like most.

I have a feeling it could just be down to perception or a little OCD. I'd say don't over think it.

Yes, it’s a colour change resin. The further it is from white, the greater it’s current organic loading.

Well Seachem advised me directly that 1% bleach solution was insufficient when I queried it with them, so there is that? 😉

I’m sure if 1% solution was sufficient, they would alter their instructions to say 1 part 8% (US domestic standard) bleach and 7 parts water - why voluntarily opt for a stronger 4% solution if it’s not necessary to fully recharge the resin?

Hi,

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 .

I've never managed to get the beads as white as when they are new. I've tried bleach only, 1:1 bleach water (as directed) and 1:2 bleach water - it hardly makes a difference in my case, that's why I am doing 1:2 bleach water. Occasionally stirring it up helps though.
Cheers,
Michael
