Dog puffer ich? Copper question

[Miller Aquatic]

So i had this puffer fish for a couple weeks and had gotten ich and i noticed scratching. I dropped the salinity to 1.009. It has been like that for a couple days and it hasn’t gotten rid of all the dots. He is still eating. In the middle of this I noticed a leak in must be the bottom seam.( this is my 55g) I am thinking of moving them to the 25g qt tank downstairs and after moving salinity back up start copper power. My question is is I used dechlorinated tap water to start up the qt tank would this matter with copper power I heard it is not good to use any products of the sorts with copper. Or did the dechlorination product already denature or whatever.

This and sponge is the only media

Sorry then, I can't tell you where the copper is going. An initial dose can go down due to calcium in the seawater, but with copper power or coppersafe, that drop is minor, and is fixed by a slight adjustment dose the next day....

Maybe I should just switch to hyposalinity or maybe cupramine I’m not sure what to do though

Cupramine is less stable than coppersafe or copper power.

The dechlorinator doesn’t make the copper level drop, what it does is break the bond between the copper and its binder, making the copper more toxic. It will still test the same.

I still can’t tell you why you readings drop. Ive had people make errors when testing with a Hanna probe, but never high then low readings. Even a meter malfunction would not give high then low readings.

Puffers handle hypo fine.
