Randy, are you doing a study of different iron-based phosphate removal media?

Randy, are you doing a study of different iron-based phosphate removal media?

Just wondering because I use PhosLock by Pura and wondered if it is just as effective as other brands.

I plan to, but my ozone articles have taken more time than expected. So I have not started the comparison studies yet.

I saw a new one. It's called "Antiphos" made by Aqualine.

It is attractive to me because a box of it weighing about 500g costs $13.00.

...but is it as good as the other stuff... that is the question.

[Randy Holmes-Farley]

I do not know.

 

[Nathan]

Any news on the research of iron based phosphate media? Have you started your study yet?

-Nathan

Randy, I have read a few threads on ozone and I am as confused as ever. Pardon my naivity but where can I access your articles on this subject? I would love to read about this topic from a fact based standpoint. Thanks in advance.

My tests are underway and will be published in www.Reefkeeping.com when done. It is a very slow process, taking a month or more for each salt mix. It is not just a matter of my time, but of allowing each addition of phosphate to come to equilibrium with the media in terms of how much it will bind. So I add some phosphate, wait 2-5 days, measure phosphate, add more phosphate, wait 2-5 days, measure phosphate, add more phosphate....

Each binding curve would be 5-20 points, and I'm doing each type at least 3 times.

The first article will compare Rowaphos, Phosban, and Salifert Phosphate Killer. It will probably not publish until the end of the summer.

I've finished testing Rowaphos and have just started on Phosphate Killer. No comparative data yet. I will say that the amount of phosphate that Rowaphos claims to be able to bind on the bottle in not consistent with reality in seawater (maybe it is in freshwater, since they lump them together, but I'm not testing that).

Don't forget Phosban Randy!!!

Thanks for doing these compairisons. Thats great stuff..

Thanks again,
Chris

Excellent!

Dont' forget PhosLock by Pura too!

I have a bunch of other materials (even non GFO) that will be tested in subsequent rounds.

 

[Volcmreefer]

What about Oceans Blend?

 

[Randy Holmes-Farley]

No, I hadn't planned to test an Ocean's Blend phosphate remover. Do you use it?

 

[Volcmreefer]

Yeah, I started using it last week. I haven't seen any results yet though.

 

[Randy Holmes-Farley]

How high is your phosphate?
