+1 biff. Avoid dosing the tank with any medications (except a couple of exceptions, like flatworm xit). Even if the meds say reef safe, I wouldn't risk it. You never know long term effects.
Why are you lowering your salinity? What was it before, and what is it now? You shouldn't raise/lower more than .001/day (although, I believe when doing a hypo salinity in a qt it's ok to lower it to the recommended 1.009 in a short time, otherwise the ich will acclimate to the new salinity, rendering the treatment useless). You should be at around 1.0024-1.0026. If you have to raise it, do so .001/day.
The kid part is a good idea :D But honestly, no need to tweak the tank parameters.
