Thats the same picture of the one I buy on Ebay. 6lbs for $66 shipped. Never had a problem with it. Lots of people on RC use it.

 

[Mark2480]

Thanks for the input that is a good price.

Hi I've been looking for a cheap alternative I'm using rowa and happy with it basicly smaller grain size is there anyway u could just grind this Gfo to a smaller grain size ?

 

[Mark2480]

Not sure but I think the picture is magnified. I use the GFO from BRS but the shipping is crazy. Tried looking at another site I was told about but there out of stock. Anyway my son saw the email and ordered it anyway to see how it is and test it out.

 

[Mattl22]

Did anyone buy from this seller???
Was the Gfo good?

 

[Mark2480]

My son got it in and swapped it out with the brs gfo since he needed to chage it anyway. Looks the same and its been running for 3 or four days and his phos level is exactly the same. So far so good.

About too order 6 lbs just wanna see if there r any reviews?

 

[Mattl22]

Ok so worth a try?

I don't think it would bring any negative effects to the tank. If anything it may not have a great capacity but for the price it's worth it, even if you would have to replace it more often.

The only thing I would think is it might leech phos back in when exhausted. Rowa cliams theirs doesn't. I am tempted to buy.

I ordered 1lb last week and the only negative i have is that the GFO granules are significantly smaller in size than TLF Phosban GFO (which i usually use).

It is a bit harder to get the flow right in my reactor with such smaller granules, also these took about 15mins of rinsing before i placed them in the tank.

As far as performance, it has reduced phosphates as expected, but im not sure about efficiency and life time of this product compared to Phosban which has larger granules that i can force more water through in my reactor.

Also shipping was quick, no complaints there.

Bottom line, i suspect i will be replacing this quicker than i do with Phosban, but it cost about $3 cheaper for about 3x times as much product.

I bought 6 lbs smaller grAnular size is a good thing in my book ill let u guys know what I think in few days when I get it?

 

[ChrisB]

Cool please let us know.

I've been using it for a while now. Its hard to judge for sure, but as far as I'm concerned it last just as long as BRS. I haven't run into any problems. As far as leaching phosphates back, I don't believe any GFO does that. The bond is too strong. It just gets exhausted and stops working.
