HI,
I have a quarantine tank that I recently converted to a brine shrimp holding tank with a air stone , I gut load those shrimp and feed them to my sea horses that are picky feeders, I started noticing that some of the anemone we acting pouty and the crabs were all sulking checked the water everything seems fine.
I decided to do a water change and I always take the old water an swap out the brine shrimp tank so they don't get to poisoned.
As I was siphoning out some water from the QT tank , I got a metallic taste in my mouth that wouldn't go away, what the,,,,
I then remembered this 10 gal was use to treat ICK some months ago even though I rinsed it several times the silicon glue in the seams was leaching small amounts of copper (malachite green) still can taste it , now I do net the shrimp and rinse them but I bet there still trace off copper in them from living in that tank. I guess I need a new cheap 10 gal in the future, I ran to my favorite LPS and bought some Seachem CupriSorb™ Filter Media it in the overflow hope it works. , geeze so many way to kill things.

Hope things work out for the better...

I have been running the CupriSorb in my tank since I started it back in March because I was afraid that the previous owner treated with copper because one of his Blue Tangs in the tank had some nasty scars on him from something. Guess that is what you have to do when you buy used equipment, it's just insurance.

hmm can you buy those pads at drsfoster smith?

HI,
The one I bought was a small bag ready to go in the overflow or filter media.
Its renewable if you go to the trouble of cleaning it per the instructions.

I may leave it in as a indicator, many of the salt mixes have excess copper in the salt mix and as we keep adding more and more salt the metals can be bound in inverts and other places even though we change the water it cant dilute the abosrbed metals, so if it turns blue I know Ive got some more of that copper starting to creep back in, maybe the bag will grab it before its absorbed in the high flow area, Lets see know I have carbon for nasties, a phos reactor that catches that phos and silica, and now a copper sponge to grab any copper that may be in the salt, pumps, rocks, silicon, shrimp..
Geeze I have headache.

well written article about whats really in synthetic salts. holy crapo its amzing anything lives.

malachite green has no metals in it.. But Light temperatures and PH all play a roll in the toxicity of it. I have no clue as to what the metal taste you got was from unless you mixed in some copper? There is a mineral salts called malachite .. And it is full of zince chloride in it.. But that woukd kill the tank as soon as it hit the water. So I'd doubt that was what you tatsed..

I run the media type in a reactor and it has done well for me.

This is what I use:

It does fantastic.

I have lots of experience dealing with a Cu problem.

Chemical sponge for removing water impurities such as nitrates, phosphates, silicates, ammonia, copper, chlorine, etc.

I have cupisorb in a strong flow from skimmer 24/7 and the Poly filter mat is a good deal also . I use the poly mat as a bottom cover in the same box to act as a floss to catch particles . I also keep the carbon in the box . I run the outflow from my phosphate media reactor also through the same box as I do the outlet from my skimmer.

But for pure dissolved metal absorption I prefer the Cupisorb over the poly mat. It does a much better job as its only job is absorbing and binding up metals Kent's also makes a good media for metals in the water..
