Depending on where in the States you reside, an adjustable filter will be needed during seasonal weather changes...and in the unfortunate event of an ich outbreak, raising the temp of the tank is the safest (and cheapest) method to control it
For the time being, do that WC to get the ammonia levels down a bit, and continue to monitor params...it WILL eventually cycle at that temp, but it will take longer than if you could raise the temp
