I have a 55 gal tank that I had established for about 20 months. A couple months ago I got sick for several weeks and let the tank get really bad. The tank has since completely died and has not had the filter/bio-wheels/or heater going for about 3 months. I would now like to start the tank back up and restore it to its former glory.
Do I need to start completely from scratch? Or can I do a 50% water change to save myself from having to wait for it to re-cycle of the aquarium. I do know that the specific gravity is way high because of the evaporation I had over the 3 months it was not running. Any advice would be appreciated. Thank you in advance.
