can Coppersafe CAUSE flashing?

[Rosenweiss]

Possibly made a huge mistake. A friend didn't like his snails so we dosed with coppersafe to get rid of them. Fish were not sick, but I was told it wouldn't harm healthy fish.

Now a guppy is flashing....

Do a PWC to dilute the coppersafe.

Just did. Phew. Seems he is not doing it as much. Did almost 50%.

Coppersafe is a bad idea unless he plans on never having inverts again. Have heard of and had unexplained invert deaths that could only be chalked up to having used coppersafe in the tank at some point in the past. Just my experience though.

Yeah, the point was to kill the inverts.

I know. I've just experienced a residual effect from it months down the line, just wanted to give a heads up.

Are you saying that once you use "coppersafe" that even after a lot of PWC, any inverts won't survive?

I'm just saying that I've had it happen and others have mentioned it also.

Unexplained invert deaths are nothing new or even rare but I've had a string of them only to make it stop by moving them to a different tank, and finding out from a previous owner that they used copper meds as their go-to treatment.

There's several articles and posts through google. I think the common idea is that it permeates the silicone seals and can leach later on, whether that's true or not I have no idea.

On that note here is a recent post on the same subject
