Ich or Brooklynella: The Battle Begins.. advice appreciated.

[Nebthet]

Well my little fishies are still alive, which is a good thing.. It is the third day in the quaranteed and 2nd day with medication.
Did a 26% water change today as per instructions, concentrating on taking the water from the bottom of the bucket, and then added another full 1ml dose of the med.
The Rid-Ich seems to be working, as they are swimming normally more and more (ie: reacting by swimming down when the lid of the bucket is lifted) and hungry all the time now like normal.

I have a three led moonlight hanging in the bucket as a subdued light for them so they don't get their schedules too messed up for when they eventually go back in the 20L.
