GFO Questions

[Neptune777]

Is there a difference between RowaPhos, Phospure without the carbon and other stuff mixed in (Dr.Foster and Smith), Warner Marine Phosar, and Phosban? Are they all the same GFO material at different prices? Does being wet make Rowaphos any more effective?

Of the group Phospure is way cheaper. Looks like a copy of Phosban..

Curious minds want to know! There is an interesting thread in the SPS forum on this but I would like for Randy to give his expert opinion....

here is a link to the phospure stuff:

There are differences that are readily apparent by just looking at them, but I do not know whether these differences translate into important potency or impurity differences or not. I'm slowly testing them, but won't have any data for a while.

Thanks Randy...I look forward to your analysis. Is thios a question you are prepared to answer now: Does GFO in a wet state (Rowa) work any better than Dry stored GFO(Phosban/Phospure)?

[Randy Holmes-Farley]

I do not see such a correlation yet. :)

From what I've read there should be no difference.

However I have an observation. Being wet the ROWAphos actually has less active (GFO) per unit mass/volume i.e 100g of ROWAphso will contain less GFO than 100g of Phosban.

So theoretically Phosban will be more economical for the same mass/volume.

Anyone care to comment?

Form a mass/volume rating you may want to look at Warner Marine PhoSar. This is a granular GFO, that is porous like GAC and has much greater absorbency.

I've never seen any useful comparative test. I have seen some published that were not done correctly.
