PolyFilters?

[Macbeth417]

I have slight problem. I tested a tank today and found it still has
about .05 - .08 ppm copper present. I was foolish and used some algacide about 2 years back in this tank (silicone seams and plastic Powerhead sucked up the Cu) and becuase I can not determine the speciation of the copper with any test I am unsure whiether or not it is bio-avaible. So as of now, I need to house some inverts in that tank for bit, but I am not sure of the toxicity of this latent copper.

Long story short: Where can I get some polyfilters locally and is this the best option (is thier a more effective resin) ?

poly filters are REALLY great at getting out copper very quickly, you can actually see them turning blue with copper within hrs. I get industrial strength ones from drsfostersmith.com. Aquaium concepts sold the standard ones, but since they aren't retail anymore i would try blue sieara, other than that marine depot has the regular poly pads.

I also get them from Dr Foster and smith.

Well folks looks like my test was reading .08 too high.
I tested it on tank water twice then on RO/DI water then on 50/50. It read about .08 on Ro/Di, .09 on tank and .08-.09 on 50/50.

Whew! So the deviation was about about .08ppm. I can handle < .01ppm Cu. Out of the 10ppb I doubt there's a great a deal of it in a toxic speciation. Nothing but happy polyps poking out of that purp tip.

WEEEEEE!

glad to hear things are fine, i'm not sure what is safe levels for corals. i have read not to put in tanks that has ever had copper in the substrate or rock that has been in copper. i have heard of people dong it after using poly pads to get it out of everything, people claim they are that good at removing copper. good luck

Seams I saw a poly filter that attached to powerheads, can't seam to find it anymore. If you know what I'm talking about I'd love a link.

thanks,

Nevermind, found it ..

Quick Filter

Would this also do the same thing as the polyfilter?

Now
I need to go find one that will work with my Maxi-Jets.

josh looks to me like this just removes particulets not chemicals or phosphates which is what you want.

Thanks for the info, don't need to remove either right now just learning.
