82 degrees farenheit for 2 weeks.
I would NOT use ich meds with the temperature raising. You would be best served doing lots of waterchanges (25% every other day for the 2 week period making sure the water going back in feels like the same temp as the 82 degree water in the tank) until the ich goes away and until there are no nitrites and very little nitrates.
If the 82 degree water is passing through the filter it shouldn't matter, and better filtration helps the fish... so I would set that up asap.
