Chemipure Blue or purigen

[jft]

What do u use in your tanks and why? One or the other if u had to choose, fancy marketing or really does what it claims to do?

Been using Chemipure Blue for months in my RSR170. Find if much easier to drop a bag in my media cup (replaces filter sock with a sponge on top) than measuring out carbon and phosguard (used to use). It is supposed to do more with the resin beads and lasts longer (few months).

Had an ICP test done a few weeks ago with a CP bag that was in there for a couple months on a tank that hadn't seen a WC in weeks. No contaminants at all (posted on build thread) to speak of.

Now is it the Chemipure Blue - I'm sure it's helping and for sure it's not hurting. Could I do same with GAC and GFO? Probably...but not as easily. I'll keep using the CP.

i use both on different tanks. It really does what it says on both of them. You pay a little extra for the convenience of not having to measure out the doses of GAC and other medias. If you use amino acids, you cant regenerate the purigen.

I like Purigen.

Chemipure has carbon in it, and carbon has been linked to HLLE.

Say what you want, but when you personally witness multiple fish develop and recover from HLLE after adding and removing a bag of carbon (respectively), that's a no for me.

The carbon in chemipure is High grade , rinse it before use the fines in carbon is linked to HLLE. personally in 40 years of using that and polyfilter over purigen always great water quality and Never an issue. Thanks.

From what I remember reading the HLLE issue was much higher with high doses of soft GAC (soft meaning high amounts of dust - Lignite). Also years ago common practice was to run as much GAC as could fit in reactor. I don't remember hearing much HLLE with low volumes of high quality GAC. Just did a quick search and confirmed that Jay Hemdal published some information on this topic that's frequently taken as "no GAC" but is much more complicated that an up/down on GAC use. For example lignite was the GAC used and also use of skimmers reduced incidence of HLLE.

Chemi-pure states using a low dust hard GAC.

I use both in my little Pico and have had great success keeping a mixed reef.

Sadly, their claims are not all accurate. Perhaps they are accurate in freshwater, and they "allow" them to "accidentally" get confounded by users to mean it works the same way in seawater.

"Chemi-pure Blue is a revolutionary filtration media that is designed to adsorb nitrogenous organic molecules, along with phosphates and to some extent even nitrates "

To no useful extent will any organic resin directly bind phosphate or nitrate from seawater.

It will, like Purigen or GAC, bind organics, and some of those organics may be exported before they breakdown to release N and P, but there is no direct binding from seawater.

Then basically FLASE ADVERTISING! SO THEN NO real difference between Standard Chemipure and the Blue is what ur saying.

I didn't make any comment on the differences between the two products, just that no polymer by any manufacturer will bind useful amounts of phosphate or nitrate directly from seawater (at the levels we usually are concerned with). There is just too much competition from chloride, sulfate, and other anions.

I idid not say you did, But by inference if no polymer and I trust your analysis then these products make assumptions that based on science DOES NOT really do what they claim they do/ No?

They may do it in fresh water. That would be the justification, anyway.

They do not specifically distinguish marine applications from freshwater applications for each specific claim.

I’ve been running chemi-pure blue for months in my nano 13.5 it’s done great. Seems like it’s kept nutrients at bay. Just dropped purigen in last night. Not sure what’ll it affect but I’ll let y’all know.

 

[Hot2na]

oh boy -here we go again...POLYFILTER..

 

[flashsmith]

Aren't Purigen and chemipure blue the same product essentially the same less the activated carbon? Most of the time I run elite with a bag of purigen. That's just how I roll but I've used it both ways and the results are pretty much the same.

Have never tried it. I will read up on it but, the chemi-pure has worked great for me. I do keep up with testing and maintenance but my tank has been consistently stable......

Do you have any idea how the ChemiPure blue and Purigen compare in terms of effectiveness at binding organics?

I am after crystal clear water and this happened instantly with ChemiPure blue for me (but not the BRS .8 quality carbon - no visible effect). I am wondering if I can replicate ChemiPure blue for cheaper by combining carbon and purigen somehow as it is a bit pricey.

I am having trouble deciphering if my cloudiness is due to bacteria or tiny particles, but ChemiPure blue cleared it right up. Maybe I just need stronger filtration. I am only using a Red Sea filter roller right now for mechanical filtration, but I also only have 8 fish in ~215g of water so load is light.

The tank is also only 5 months old so maybe it just needs more time to settle?

I have recently read a study that states exactly this in which case Boyd are making false claims and cannot use the excuse that it probably does work in freshwater tanks as Chemi pure blue is specifically targeted and marketed to saltwater fish keepers as stated on their lab “Superior filtration for Reef and Marine Aquariums”.

What sort of study did you see, and do you recall where you saw it?
