White spot

so i had ick and i put all my fish in quarintine and left my tank fallow for 8 weeks, everythings about ready to go in and showing no signs after treatign with copper but i still have a fire fish, a sail fin tang with a single white spot on both of them thats been there about a week, copper is still in the water is there anything else this could be, and i also have a watchmen goby that on his fin has like a foggy area on the edge of it, could that be ick? iv read alot about it but i wanted other opinions.

 

Are your copper levels residual? I mean have they fallen off from where they need to be to be effective?

 

no if anything they maybe alittle high im using copper safe and putting as much as the bottle tells me to put in and alittle more

 

How long have you been treating them? Usually takes 3 weeks for everything to disappear. I would like to say that the spot on the fin is not ich, but I would really need to see a clear pic

 

ill see if i can get the pic its rather small and theyv been in for 8 weeks

 

If you have been treating with copper at the recommended dose for 8 weeks, there is no way it is ich. What kind of test kit do you have for copper?

 

no test just putting the amount hte bottle tells me and hten alittle more

 

ok this is the best picture i could get of the goby if you look on the fins you can see it.

 

Well, I hate to say this, but if you havent been testing the copper level you really have no way of knowing if it was high enough to be effective. So even after 8 weeks, ich could still be present. There are a lot of things in your tank that will soak up the copper, pvc,filter, etc. and depending on what type of copper product you are using the directions on the bottle don't really apply. and if your levels don't stay high enough and stable, then you really don't know for sure that it has been eradicated. I would highly suggest ordering a salifert copper test and find out what your levels are and dose for 2 more weeks at the accurate levels.

 

The answer is probably frustrating but it is true. Unfortunately, that is the best course of action you should take given the situation. Although, I'm sure you would rather be confident that everything is better before getting them back in your DT and having another outbreak.
