Velvet Treatment. Complete Darkness?

[kinmad4it]

I stupidly went and got some new fish from Pets at Home on Friday. Will not make that mistake again.
I don't have a quarantine tank and didn't notice the little gold dusting the black dalmation mollie had until she'd been released into the tank.
I've added Methylene Blue and done a 10% water change and also draped some towels over the whole tank.
What I'm really asking is, should the tank be in complete darkness? And will the fish be ok with little or no light getting into the tank?
I do keep pulling one of the towels back every so often and popping the light on, just to check everyone's ok.

I can't see methylene blue having any effect on velvet.
treatment should be with a copper based medication (Oodinopur A by Sera, Cuprazin by waterlife to name but 2)

yes treatment is more effective in total darkness as the parasite needs light to survive

It does say on the Meth box that it is a treatment for velvet. However, if I want to get a velvet specific treatment, would it be advisable to try and get rid of the Meth Blue first? Or can different treatments be added at the same time to the one tank?

I've got some Interpet velvet treatment. But the tank still has some Meth blue in it. I've done 2 50% water changes and the water still looks pretty blue.
Will I have to make sure all the Meth Blue has gone or can I add the interpet treatment now?

Run some black carbon.

Thanks for the advice
Presumably I can just pop a carbon filter pad into the Fluval? Wont it need to have been matured first or not? Also, and sorry for all the questions, what do I do with the matured normal pad while the carbon one's in? And how long should I give it to remove all the Methylene Blue?

the carbon pad for fluval are designed to fit in conjunction with the other media.
run the carbon for 24 hrs and then remove and start the new treatment.
