Not anecdotal claims at all.
Test your reactor output from time to time(it will raise as it ages, meaning it's leeching back out). Or just read some of randy's articles.
How do you GFO?

Thanks for the non-answer. I suggest you do the same. Feel free to cite your references with links, thanks

Non answer? Just test the output of your reactor after a time. What article do I need to cite for that?
I have no need to argue with you, if you don't believe it, then thats fine too.

Thanks for the help, make claims then tell other people to figure it out. Ok I’ll chalk it up to you being incorrect. Professional poster over here, gotcha.

Not even worth replying to.
Thank you for not contributing anything to this discussion. Move along now, thank you.

if you don’t see the hypocrisy of your own post... still waiting for those citations..

In particular
Discusses GFO releasing adsorbed phosphate back into the water column..

Thank you. I just don't have the patience to explain things to people who are so adamant on their stance.

Ah so, if you read what is said there is it will find an equilibrium. The key being ‘when the aquarium's phosphate concentration drops low enough.’
nobody is taking used gfo and adding it to water with no phosphates in real world practices, nor does it mention how much is made available.
How we use it in our aquariums is quite effective and when it’s exhausted you simply replace and ultimately you end up at a net loss. Imop the downside is drastically overblown as of late by a few folk
You’ll notice no mention of it in the article specific to GFO as a potential downside.
“The bottom line: Would I use GFO to export phosphate? The answer is a qualified yes.”

likewise, coming in making claims but can’t be bothered to cite anything or be helpful. Simply toss a belittling qualifier to the start of your post about what ‘expert reefers’ do as if we should all take head because of some self proclaimed expertise. “I’m right if you don’t believe me figure it out I can’t be bothered’. That’s some RC attitude right there.

So my experience without a citation of some sort is not valid? Never said I was an expert of any kind either.likewise, coming in making claims but can’t be bothered to cite anything or be helpful. Simply toss a belittling qualifier to the start of your post about what ‘expert reefers’ do as if we should all take head because of some self proclaimed expertise. “I’m right if you don’t believe me figure it out I can’t be bothered’.

You might just want to move along, Ive searched your post history, You holier then though attitude does this forum no good. Were here to help each pother, not belittle each others experiences.
I've read the articles and have my own experiences of which I speak. If you don't want to go find the same articles without being spoon fed the information, thats on you, not me. The new forums, if you don't spoon feed me information thats widely available, and easy to find, then your just plain lazy and no help.
I come from a time when people did their own research, not rely on others to spoon feed them information. Sorry, just not who I am, or who I want to be.
My last word on this, as we are truly derailing the thread.
You might want to go back to RC with your attitude.

You literally are saying what you are doing and putting it on me.
Try being actually helpful understanding people are here to have open discussions, if you make a claim provide the source, and be OK with people wanting to have a conversation. Don’t expect people to take your word on it; or run some science experiment to prove your point simply because you say so.
might what to take a little of that medicine you’re prescribing.
Yah sure, I’ll move on and go back to RC when you stop spamming to get your post count up, smh what next do you want to debate some ridiculous notion of forum seniority post count vs join date hahaha.

I did not realize GFO was such a heated topic. I wasn't expecting my question to cause such a problem.
I have simply never used GFO and was looking for experience from the masses. I was hoping I could just find a fine filter bag so I could start off by running it passively before I had to put in the effort in plumbing a reactor.
I DID get the information I was looking for so thanks everyone for the great conversation.
Stay calm and keep reefing

What is your method for Lanthanum Chloride? If I wanted to add it undiluted, what would you recommend I do? Drops directly into the skimmer? Filter socks?

I was under the impression that GFO did NOT leach phosphate back as well. Can anyone else comment on this?
Any structure that binds phosphate only does it at equilibrium with the water level. Add more to the water and it will bind more... change some water and lower the water level and it will release some. This is also true of aragonite (your rock and sand), calcite (maybe your rock) and aluminum oxide (phosguard).
I know that BRS probably does not cover this in their infomercials, but it is pure science with discussion and articles back to classes, books and papers back before I was in college.
Other things to know about GFO is that it can get covered in organics pretty quickly and not be effective anymore. Another reason why passive and/or long term use does not work well and will just likely waste money and product.

Do you know if it leaches phosphate back? My method-for my way overstocked and overfed 120-was to put lots in a reactor and just let it run. I'm questioning this now.I did not realize GFO was such a heated topic. I wasn't expecting my question to cause such a problem.

...not that it matters much in a reef setting, but dolomite would also bind and unbind the same as GFO, Al Oxide, aragonite, etc.
With GFO, if you just do small, quick runs and test with an accurate tool like a Hannah Ultra Low, then you are going to likely be good. Lowering phosphate is fine, doing it too quickly is not a good idea. Being efficient when using it can save you a LOT of money.
Edit: I have lots of thoughts on Lan Chloride. If somebody has questions, start a different thread on the usage and stuff and invite me if you care. Some of the same principles apply like planning, allowing and waiting for phosphates to unbind from your rock as sand as you remove them.

Likewise, I’d be curious to see if @Randy Holmes-Farley would chime in, and what is the amount and/or catalyst required for said conditions to take place. Based on the articles I’ve seen he’s spoken of following up with actual tests vs theory but am unsure if that information exists and the articles folks (including myself) cite are decades old at this point.
I’ve found the long term use of GFO has always resulted in a net loss of phosphate and have years of logs to back that up. YMMV.
