Dr FS Phospure Users

[HAVIC]

I just got the phospure from Dr. Foster Smith and put it in my phopsban reactor. the gfo from them comes wet as opposed to phosban which is dry. The main thing I noticed was that when flowing through the reactor it does not flow as nicely as the phosban did. What I mean is I either see next to no movement on the surface of the gfo with lower pressure or when I raised the flow through the reactor the media just started to throw particles all throught out the column.
Is this just how wet gfo works or should it look the same as the phosban when running (ie. percolating). I'm not sure if my new gfo has clumped or not because I did not have a problem with the phosban in the reactor.
Thanks
Greg

I gave this stuff a try as well. I dunno exactly what it is, but it sure looks just like a phosban and carbon mixed up. Phosban and carbon require differing flow rates for optimal performance so I doubt that phospure is as effective. The phosban-like particles are a bit bigger than phosban, so I think it makes sense that they shouldn't be shimmying around on the surface.

LMK how the results are. I was thinking of getting it myself.

I think you are confusing two different products. There is PhosPure which is straight GFO, and then there is PhosPure? plus Zeolite & Carbon, wich as the name suggests has carbon and zeolite for amonia mixed into it.

you are correct. my bad.

Which one is better. PhosPure or PhosBan by TLF?

there is an article out there that I will try and find that says that they are all pretty much the same. Phosban, phospure, rowaphos are all GFO with is granulated ferric oxide, i.e. it is rust. There are different types of GFO, that is why some are packaged wet, while some are dry and they come in different particle sizes. The amont of phosphate that can be absorbed depends on the microscopic structure of the particles.

The article I read tested Phosban and Rowaphos and found that while rowaphos was more effective, it also cost more. When they results where broken down by amount of phosphate removed, by the number of dollars spent, they where the same.

Phospure was not tested. But considering that it costs a lot less than the others, it would need to be alot less effective not to be cost effective.

That is exactly what I meant. PhosPure is half the price of the other two so I was a little bite skeptical in getting it w/o hearing from a fellow reeferer the results.

I am going to try the phospure ( I actually split 1/2 of the package with HAVIC so that we could try it, but havn't picked it up from him yet). Once my Hanna Meter comes in I will let you know.

For what it is worth, there is absolutely no reason that this stuff needs to be expensive. Granted there are quality control issues and stuff like that , but in reality it is nothing more than rust.

 

[crox99]

I know that is rust!!!! BTW did you order the Hanna?

 

[meschaefer]

I have the hanna on order from Drs. Foster and Smith. Based on my e-mails with Hanna Instruments, I hope to have it by the end of this upcoming week.

 

[crox99]

I probably going to order it in a day or two.

 

[alfani]

i'm running low on rowaphos and thinking of getting the phospure from Dr F&S. any one have results, besides being dirty, are they any good

 

[scumonkey]

Correct me if I'm wrong...
Isn't Rowaphos the only product that will not leech back out after reaching full absorption?
