Safe Again?

Not really sure where to post this as it has to do with illness but its not an emergency.
.
So... I've had a rough bit of luck in one of my tanks and my population has gone from about 50ish guppies to 10. I know what the problem is (not exactly how it started but it doesn't matter at this point). I am hoping these last 10 will all survive.

I do have a second tank with 8 male guppies and 3 females in it (I would not normally have that ratio of male to female but it was desperate measures early on to get the healthy fish out of my tank... I decided it was worth the risk, and that has paid off... great health in that tank still).

ANYHOW... still battling disease in my onw tank but my remaining 10 guppies seem minimally affected. My question is... how will I know when my tank is safe to re-introduce the females that I had evacuated and introduce some new residents for restocking? I know its not time yet... but I don't know at what point it will be safe to add fish and not have them come down with disease. (In case it helps I am dealing with fin rot and some sort of fungus... the fungus seems to be 90% under control now and the fin rot seems to be teetering on being under control... just need to see that turn that tells me things are improving rather than just not getting worse).

So... what time frame should I wait so I can safely add fish to my tank? I find it a bit hard to judge with the fin rot. Do I wait until I see new regrowth occuring?

I have no definite answer on this, but recently I've had problems in a couple of my tanks, these tanks went into lockdown (nothing in or out) until 4 weeks passed with no deaths or apparent disease.

After 4 weeks, my Microsynodontis ( three "sp. 1"s and one "polli") went back into the 48x12x15 community and all is well some 2/3 weeks later (aggression from the ~30 Ilyodon xantusi fry became top suspect to 7 deaths, only 1 of those happened after the goodeids and catfish were seperated and that happened ~30 hours later... The bizarre thing was that the 8 Ilyodon parents were in the 48x12x15 together with these little catfish for ~6 weeks back in March with no issue).

My 5x2x2 is still in lockdown, having lost three fish (Redline Torpedo Barb; Panda Garra; Golden Wonder Killifish) over the last ~7 weeks, the last death being 8 days ago just before the Esha 2000 meds arrived. The meds has made a big difference down there this last week, but one Torpedo Barb still has what seems to be a healing open wound. Once that has cleared up and no other issues appear to be present, I will start the 4 week clock, it is rather annoying as I want to move some fish down there and move others out... But I do not want to recklessly cross-contaminate my tanks.

4 weeks sounds like a good target. My worry is that my females in the male tank might get stressed from all the attention. And the annoying thing... I have a third tank but the filter I would normally put in there is in the large tank (as to keep it cycled) so I couldn't just transfer it and start my third tank up.
