Whitespot treatment.

Hi I noticed my fish scratching themselves on rocks, 3 or 4 of the tetras, and also noticed white spots on the fish in the tank affecting 3 of the tetras most probably about 6 or 7 spots in total on the tail and anal fins of the fish.

Action taken so far...

I've added 3 tsps of aquarium salt, removed activated carbon from the filter and added 10ml of tetra contraspot and 5ml of tetra generaltonic all mixed in aquarium water outside the tank and added slowly over an hour or 2. I have also gradually upped the temp to 26.5° (not brave enough to up it more as I believe that is outside the tetra's temperature range) and also increased the aeration of the tank.

Is there anymore I can do?

I intend to add another 10mls of the contraspot of the course of the weekend and do a 20% water change on Sunday cleaning the substrate as well. The fish have seemed to slow down on scratching themselves against things.
My only concern is that the nitrate is partially up at .25 ppm and has been for a few days but hasn't increased further, and I am monitoring it daily, will the removal of the carbon and addition of the medicine affect this?
Ph is around 6.8 to 7, and ammonia is 0 FYI.

Any advice would be much appreciated.

 

I don't think there is much more you can do now you will have to wait till Sunday and see if the white spot is still in the tank.. But I am sure you can up the temp a bit more to about 28 the tetra should still be ok with that...
