discussion and isotherm charts between DD Rowa & phosban, but I don't know of any between Aluminum (only one company still sells this stuff) & GFO.
anecdotally, on June 8, 2006 I started using Phosguard, my phates reduced but not low enough and on June 27 I switched to ROWA, and immediately my phates went "undetectable" with test kit that I was using at time (Salifert).
So, you may disagree, but I have years of experience with a product that works that is well supported by the "reef chemistry" and SPS community. I don't need any "proof" because I can look across the room and see it! Year after year......
Do either of you have "proof" other wise besides an incentive to sell stuff?[/QUOTE]
Im not sure what this is proving really. The first link defines the materials. Good- Im not sure this was in debate. But it goes on to state that GFO can rather easily release phosphate back into the water. Not a good thing in my book.
In the second link, the two comments to the article are very telling. Read them. This was written ten years ago too. I have contacted RHF and asked him him thoughts re his article, and the one I posted. They say very different things.
In the other links, I don't quite see anywhere where he says anything other than "this is what I do". Not that one is better than the other or one is a waste of money, etc.
[QUOTE=][B]mysterybox;858722 wrote:[/B] Ok, here is a study on the effectiveness of various phosphate removal products by Prof Dr Ing M Jekel, Technical University Berlin, Department of Water Quality Control.
it contains isotherm charts
reviewed are Rowaphos (Iron based), Elimiphos (Aluminium based) among others....
just saying...............:tongue:
I also believe that most aquarists looking to move into the realm of sps, will need to understand how important removing phosphates, trates, and the managing and maintaining of bacteria in their system in a balance way.[/QUOTE]
A couple points on this- 1) it isnt testing phosguard. Its testing Elimiphos. A different product made in a different country with different criteria and standards. And we both know Ralph, that all are not made equal. Thats why you run Rox carbon and Rowa, not generic brands, right? But beyond that, what am I supposed to be seeing. Please, <u>[B]tell me[/B]</u> what this says. Again, "efficiency" defined how? I need you to decipher what this says for me, and show me where it says it.
[QUOTE=][B]mysterybox;858788 wrote:[/B] Ummmm, if you read my last post there is an actual study with factual data....showing that Iron based ROWA is more effective than Aluminum like Phosguard, lol.
Most reefers consider Randy Holmes-Farley more knowledgable than just "discussions from other forums"....
Continue to use what you like, even though the evidence and support states otherwise......[/QUOTE]
RHF is a very intelligent man when it comes to reef chemistry, for sure. But, c'mon man, you cant just blinbdly follow what he says and do what he does, without understanding it. So, rather than say "Its what RHF does, and he's smart", lets help out by explaining what and why.
mind you, this was a fowlr with a few Lps and softies. Since I plan on moving all my coral over, that would not suffice. I put 1/2lb of GFO in a sea systems reactor and let it roll.
