I'd drop the temp (SLOWLY, depending on the stock) to 75 deg F, 33% to 50% water changes daily or as much as you can stand to do, and bring in some filter media from the home tank.
A good UV sterilizer will help.
An hour or two if daily direct sun in the corner can do more than you may think, reduce the lighting. 8am - 3pm would be my guess.
Can you get us a pic?
