Mouse:

Yes, Mouse, I'd have to claim that your advice was bad. You gave a lot of inaccurate information. If you consider my corrections a flame, which IMO were useful additions to the discussion, so be it. I think I can live with your condemnations.

What does it matter if you sell it? Well, a lot of people who sell things claim their products are the best with little or no supporting information, and a vested interest in making such claims. I'm glad to hear that you have no such vested interest. People without such interests don't usually post ALL CAPS sentences about what product is "THE ONLY OPTION".

Are you actually claiming that you would want a tank with NO phosphate in the water column? Every living organism needs phosphorous to survive, and many get that from the water column. Maybe you should read the article that I wrote on phosphate, and we can restart this discussion:
http://www.animalnetwork.com/fish/library/articleview2.asp?Section=&RecordNo=2481

If you are saying that ROWAPHOS is the only way to reduce phosphate, and you are not even aware of iron-based products for phosphate removal, then you have no business giving such advice.

No, you needn't explain mechanical filtration to me. But I would like to hear how mechanical filtration will substantially reduce phosphate. Most people believe that such filtration, as typically employed, results in higher levels of nitrogen and phosphorous compounds in the tank water.

PS There are no condoms in natural salt water.

OK, lemme list what I know about the situation and hopefully Randy et al will be able to fill in the blanks.

Rowaphos is not new on the market (I assume you mean the UK market Mouse?), however fairly recently a more formal import mechanism (from Germany) has been established.

The product is in its second incarnation. Orginally it was a colloidal gel, now its a damp powder. It is Iron oxyhydroxide (FeOOH). It is claimed that in this form it releases no Fe, again it is claimed that the other various iron based products do.

wrt the Aluminium based products it appears that they release some Al into the water column. Over time it is claimed that this is a bad thing.

See for example Lars Sebralla's website for independent (?) testing
web page

Is Rowaphos the "only" way ... no of course not! However it is interesting to consider the potential pitfalls of the other products. Now whether Rowaphos has its own set of weaknesses I have no idea. Hopefully Bingman will be able to provide some answers shortly as I believe he's testing it soon.

Randy, 1 thing I would question from your post, you mention PO4's being >0 in NSW, sure, however PO4 in aquariums is considered "zero" when several magnitudes higher than NSW. Or is this not the point you were making?

FWIW

Andy:

I agree with you: NSW is substantially lower in phosphate than what many hobbyists would call zero. I just wanted to be sure people knew that phosphate was there in NSW and was needed at some level.

FWIW, Mouse and I straightened out some of these differences off line.
