I have 3 silver lyretail mollies and one sunfire platy in a 10g tank.* I have had them for 2 weeks in a tank I had setup for approx a month.* The velvet came back it seems

* They just started showing signs of it again today, have gold dust on their gills, rubbing against things and darting about then sitting at the bottom or resting on the top.*
I got my test tubes and here are my readings:
PH 7.8
Ammonia .25 - .50 it's fluctuating
Nitrite - 0
Nitrate - 5
I'm gradually putting the temp back to 82, the tank is partly covered to let them readjust to dark.* I treated the tank with the Maracide.* Is there anything else I should be doing to treat them?* I am going to watch the ammonia and do water changes every 24 hours as needed before treating with the maracide.* I don't believe my tank has cycled yet but I guess time will tell.
