Ok I was told that its could be the very beginnings of brooks or bacterial issues -- he suggested using Metronidazole since it will fight against both and can safely be added to the DT tank. So the questions is should I go with this treatment or copper again and if going with copper instead of using copper power I should try coppersafe?
Sorry, I don't have any experience using metronidazole with invertebrates as I've only ever dosed that orally or in a treatment tank.
Without knowing their exact ingredients, I can't say for certain, but the consensus seems to be that Copper Power and Coppersafe are essentially the same. Copper Power used to say dose at 2.0, but I heard that they changed their package instructions to say 2.5. Coppersafe is 2.5 at a full dose.
