GFO

[Pistol]

Who regenerates their HC GFO, What do you use? Do you have any issues?
I use Home Hardware brand bulk lye, the MSDS doesn't list any other chemicals but doesn't state that it is 100%.
It seems to work and I don't have any issues, I pay about $20 for 3 kg of lye.
Just wondering what OP are using.

Interesting. Did not know that GFO can be regenerated.

I checked another MSDS from Fisher Scientific. Their product has Sodium Hydroxide (>95%), Sodium Carbonate (<3%), and it still not making 100%. There is a big chance that there are traces of Potassium Hydroxide and Potassium Carbonate. Sodium and Potassium are "close" metals.

Another byproduct from manufacturing process can be Sodium Chloride, so there might be traces of this, too.

Whatever I listed above should be safe for regeneration.

I am not sure if any traces of chlorine, hypochlorite or similar are present.  :-[ I would say that even if there are, they will be consumed or washed out after reaction.

If any other heavy metals are present, I do not think that they would replace the Iron in GFO.

Yes, this is the link for the process I am using.

Thanks for the info.

Seems like a lot of work to save a few bucks... and time is valuable...

Interesting. Didn't know this stuff could be brought back.

It's not a lot of work, it sits in a bucket for 72 hrs, I like to rinse mine in stages to allow it to leach for a while.
I hate paying big bucks for RUST.

A dollar saved is a dollar earned I guess.

need to keep the old used stuff I will take it off your hands if you want.... I am building a collection to regenerate at least 5 gallon pail at a time.

I'll stick to my 500ml a month.
What are you using for sodium hydroxide?

I use the Home Hardware lye as well.  For the few bucks it costs, it's easier than bringing caustic solution home from work...

When its due to recharge, I just pull the reactor off the tank and swap it for the second that I have recharged.  Never open it or mess around with the media.  I recharge about three or four times until the particle size starts to get too small.

You folks are doing any testing for phosphate in the final solution? Or just follow the process?

Any idea what is the difference between GFO and HC-GFO? Other than absorption capacity. Porosity, size, chemical composition? What makes it high capacity?

I'll find something to start saving mine for you in.  Heh, to me 'lye' and 'sensitive reef tank'  don't mix     However, I'd be happy if it's not just going in the trash

Remember 30 years ago, good recording tapes. You would not throu those in the trash . Just little bit pH raiser

Lye is just Sodium Hydroxide (NaOH), so even if you did a lousy job of rinsing, all you're going to put in your tank is a few sodium ions and if you use calcium chloride as a calcium source then they will just help to balance the chlorine ions.

i use lye in the hot tub to help with ph as well

I dunno, I used to get rid of all my dead hookers (before I found Brandon's hooker removal service) with lye.

I just follow the process but with 50% more rinse to be safe.

You said it all, absorption capacity, porosity, size.

To help with WHO?

GFO is pricey, If it can be regenerated then why not try, another good read.
