 Topic: Copper
Posted: February 21 2015 at 12:50pm |
I did a really grave mistake putting brass connector on my pump a week ago to my 18 gallon tank. My corals were closing and I cannot really figure out what happen so I took them to my friend. I thought it might be because I used too much epoxy on my aquascape.
I read online. People said that I should dump all my LR LS and start a new tank. This is very frustrating because this is my very first salt water tank.
Thanks,

So sorry for your troubles. I'm glad to be of assistance. Texting is so limited. Now I have time to fully explain.
That amount of time was not long enough for any significant amount of metal ions to ruin the sand and rock. How do I know this? 1. Because your coral started perking up almost immediately after we placed them in my system yesterday. Today most of them are looking very good. There was no permanent damage. 2. Also, brass by it's own physical and chemical makeup (Copper Zinc alloy) is fairly inert in water. Brass is used for water fittings because even just a little corrosion on the surface of the metal can take years.
The sand and rock is okay. Don't throw it out. My guess is that what you may have been reading or heard from an uninformed LFS was about not using sand and rock from a tank that was treated with copper based medications.
Even if there is a little metal in the water or a tiny bit that bonded to organic material in the sand and rock, I'm pretty sure it was a very tiny, almost insignificant amount. The use of Chemipure for just a week should remove the metallic ions that may be contributing to the coral issue.
The most troubling factor in this instance, I still believe is the epoxy. The coral became irritated by the chemicals in the epoxy. FYI, when this much epoxy is used in larger tanks, the skimmer foams like crazy. Skimmers work by the creation of bubbles that form, held together by organic chemicals. It's similar to the bubbling action of soap. Soap and skimate contain one or more of a group of organic chemicals that are scientifically classified as Surfactants.
The Epoxy leaches Surfactants into the water. Surfactants can irritate coral and fish because of how they stick to fleshy surfaces. Fish can move water over their gills to help keep them clean. Corals only defense is to produce a layer of slime, as it shrinks, to shed the chemicals. Water movement is the only way that slime can wash away (That's why flow is so important.). In the case of this relatively large amount of epoxy, one shed just wasn't enough. The coral ran out of energy to slime and simply shrank up, waiting and hoping for the water would clear up.
This is what I believe happened. Is this making sense?
Aloha, Mark  |

Oh, one other thing I believe I shared with you but almost forgot to mention here. Your tank water tested ~0.10 for PO4. That's a little high so come visit again as soon as possible and I'll give you a little bag of AA to remove PO4 from the water. Free.

I used Cuprisorb from Seachem for four days. Today, I bought a copper kit test, and it turns out to be 0 ppm. However, two corals that I left in the tank still dying. Any opinion? Thanks

Some copper needs to be tested with different tests. Just fyi

Ohh, I did not realize that. I might have to buy the Seachem test kit.

Cuprisorb took out all the deleterious Cu if there ever was any. I would not spend money on another Cu test kit. It isn't necessary IMO.
I really believe it was the surfactants produced by the curing epoxy. I'll go look for threads here and report back.

Two of many comments I found here in this forum about epoxy: " A skimmer can pull out even the tinyest amount of soap and turn it into a bubblebath, trust me , I know first hand. Also, my skimmer will react this way if I use that epoxy clay for adding frags.""I have never been a big fan of the epoxy putty ,clay, whatever. I can never get it to work like I wanted either. And if you use too much at one time, your skimmer goes crazy for a few hours. I just use the gel or just put the colonies in cracks and crevices."
I'm thinking that if your skimmer didn't foam like crazy when you used this epoxy, it may be that it's not a very efficient skimmer, OR it may be the wrong epoxy or a bad batch. What epoxy did you use?

I've never had a problem with epoxy before, and I've used tube upon tube upon tube.

Did you change anything else other than the copper connector?

Come to think of it, my skimmer foam like crazy as you said Mark. I thought it was normal because I have the skimmer for just two weeks. Total newbie I am. Lol
Phys, I changed the brass connector and also did rock scaping with two chunk of putties.
Now, I notice that my devil hand is getting better though.
Thanks

Was it new rock? Did you have it out of the water for a period of time? If either of those, you may have seen a spike in ammonia or nitrites due to a small amount of die off.

I used live cure rock though. However, I dont think that is the case because I changed water everyday when I notice that my corals did not do well.
