In the short time I've been in this hobby, there have been three categories for copper dosing as it relates to the DT. Yes, copper will kill corals and inverts, that is not debatable. Make no mistake. I do not intend to bash anyone who falls into any of the categories. My goal is to try to provide some clarity in the clouded space of the world wide web(WWW). This journey is not intended to be the "best practice" in reefing. I intend to provide others with some evidence so they can make an informed decision on how they want to proceed if you happen to find yourself in the same position as me. I get a little long-winded at times, so bear with me. I'll let you know upfront as of two days ago (4/17/20). I began dosing copper to my DT. Read below for further.
Category 1, "You cannot, under any circumstances, ever dose copper in your DT. You will never be able to keep corals. Your rocks/sand will forever leach copper back into the water column." We have no shortage of people in this camp. They seem to be the majority by far. I have never seen a post from anyone who dosed copper in their display tank. Then after the dosing was unable to remove it, causing long term failure. It's usually quoted from reef urban legend or reef well-known fact. I mean no offense by that at all, I blame the internet for this problem. Please feel free to correct me. I will not be offended. If you are one of these people, please post below. Leave photos and a short story to help the community. It would be helpful to have this information in one place.
Category 2, "You absolutely can dose copper in your DT. After the treatment is done, you have to make sure you run a copper remover and get a 0 reading. Run a few ICP tests to be sure, and you will be all set. I've done it myself, and now I have a successful reef, look at my pictures." These folks are very few and far between. Not many fall into this category that I've been able to find on my searches. They are by far the minority. I don't know if that's because people don't post or some other elusive reason. If you are one of these people who have found success, please post below, even if it was short term success, if you've had long term success even better.
Category 3, "I don't know who's right. I don't know if I'm just looking for the answer I want to hear because it is more convenient for me(known as answer shopping). Or, am I in denial of the truth: you cannot dose copper in the DT. Lastly, everyone is afraid to go against the grain/ risk the thousands they have spent on this hobby, which is completely understandable? What am I missing?" This is where I find myself.
Because I fall into category 3, I'll tell you how I got here. And what lead me to ultimately dose copper into my DT. I will try to make it brief. I ordered a Red Sea 625xxl and got it all set by the end of January 2020. This tank replaced my lightly stocked 125 gallon, my second saltwater tank. I filled it with brand new Marco Rock (that had been cycling since Febuary 2019 for this purpose). I decided to go bare bottom this time around to make things low(er) maintenance. I have heavily invested in Apex and watch a lot of BRS videos. All of the fish stock transferred over to this new tank, and I added some new guys as well. I thought I did an excellent job QT my fish, but to my surprise, I did not(sarcasm). I had what I thought was velvet, which may be ICH (see my pictures below, and you be the judge). Regardless, as the disease progressed, I saw a bunch of spots that appeared to me and all my infinite wisdom to be velvet. Instead of losing all my fish, I decided to dose my DT with copper.
The tank stock:
1 Yellow Tang
1 Desjardini Tang
1 Powder Brown Tang
1 Hippo Tang
1 Coral Beauty
1 Matted Filefish
1 Pink Watchman goby
1 Melanurus Wrasse
1 Midas Blenny
1 Chromis
1 Royal Gramma
2 Lyretail Anthias
2 Ocellaris Clownfish
5 Zebra Barred Goby
When I started seeing spots on the Hippo tang, I got worried. I referred to the internet, as most of us do, to try to find some resolve in the situation. I have only been in the hobby for three years, but I researched enough to know that I don't know that much, lol. As we all do, I found @Humblefish, @HotRocks and @4FordFamily threads and used those as a guideline. But I also have so much respect for @Paul B and take note of his natural apprach. However, when the Hippo's spots quadrupled in one day, then multiplied on my powder brown and a few other fish as well, I referenced internet photos and believed I had marine velvet. I felt I didn't have the time to ask the internet to confirm my suspicion. I went over my options weighted everything out and decided I was going to dose copper and document the outcome for the rest of my category 3 folks.
I had too many fish, and I did not have a QT tank to put them all in. I'm aware I could have purchased a rubber made tote and put the fish in there for 76 days while the DT ran fallow. But maintaining a large plastic bin of water was not in the cards for me. If this turns out to be the worst-case scenario, I will replace the rock in my DT and start over.
My plan is to document the progression of this and see if the rocks absorb notable amounts of copper. I will post the daily copper levels from my Hanna Checker to this thread to keep track of things. I will also do my best to keep those interested informed on the progression of this dosing experiment.
If you have any comments or suggestions for me along the way, anything is welcome. See the attached pictures.
@lolmatt Thank you again.
