Lice Attack!

[klinker]

I seem to have a reoccurring problem with lice (louce) in my tank. For the last three weeks I get rid of them then they come back 3 or 4 days later.
I have been treating the tank with Aquatronics Dyacide but I have been finding it more effective to remove the fish from the tank and put Potassium Permanganate on the lice and wipe it off.
The lice seem to come back after I feed my fish Hikari frozen tubifex worms.
Is it related?
What are the chances that lice could survive freezing?

The background – My tank has been set up since Christmas and was cycled for 2 weeks with some feeders. It is loaded with live plants that were bought before the fish were added. Then mid January the lice started showing up.
Water quality is amazingly clean, water changes every 7 days.

Am I totally off? Is there some better way to treat my tank?

"In water" medications such as Fluke Tabs, Clout, Paragon or Trifon may be helpful. All fish as well as the aquarium they inhabit should be treated to prevent recurrences caused by unseen free swimming juvenile parasites. other good meds include:

Kordon TM - Aquarium Trifon
Oxolinic acid. This chemical is available in 200 gm bottles

I'll try the Aquarium Trifon first. the Oxolinic acid looks pretty serious and I don't want to have to do a complete water change!

Thanks

I would suggest that if they return in 3-4 days you have not gotten rid of them.
