Ich

[Richards Aquarium]

This is my tank 75 gallon. I just want to do the treatment with copper in the display tank. I'm just looking for how hard is it going to be to keep it at the recommended level of copper and how much copper should I expect to buy. I want to get rid of this and I'm not doing a fallow tank for 75 days. I have my reasons. Please and thank you. It's all live rock and 3 inches of live sand

Copper will leech into your rocks and substrate. This will make correct dosing very difficult and will have lasting effects. Also is toxic for invertebrates.

Here is a detailed explanation.

If you are sure of the ich diagnosis, I would consider hyposalinity - that will cure ich and flukes without the residual copper issues.

Hyposalinity

Hyposalinity Jay Hemdal 2021 This term refers to a long-term bath treatment for marine fishes in which the salt content of the water is lowered and held below the point that certain parasites can survive. The salt level reached, and the time of the treatment are the two variables...

Since you ask, I’ll answer. Ive done it at least 3 times in the past. Obviously I had no corals/inverts in my Fowlr (500+) when I did it. I twice treated with cupramine in the past (using API copper test kit) before being aware of the Hanna test kit (the only test kit to get) and then ran curprisorb and polyfilter pad to make sure copper is back to negigable levels (2-3 months). I then put back in shrimps, nems, cuc without issues long term afaik. Those same shrimps, nems have been going strong years later 2.5+ years.

Just last year I treated my 500g fowlr with coppersafe (which I recommend over cupramine). I am now running Cuprisorb again to get rid of the copper. I’ll leave the Cuprisorb in for 3-4 months to get any remnants and run a polyfilter pad at the end too for polishing out any leftover copper.

There will be about 2-3 weeks where you’ll get an idea of what your copper level is and how much is being absorb by the rocks/sand. (I find with my calculations that I have to dose almost 3 times the amount of copper to get and hold the right amount of therapeutic level over the period of the treatment versus if it was a bare qt setup.

Of course, if I can catch and house my fish in another ‘bare’ qt, that would be the preferred method but sometimes that isn’t feasible.
