It may or may not die but I don't think it's fair on the fish to try it!
You don't need to be constantly feeding and empty tank you can use one block of frozen food and that should do it.
After about 4 - 6 weeks you should have 0 nitrites , 0 Ammonia and nitrate close to 0 as possible. Then add one small fish. Leave it for another 3 - 4 weeks and add another! Take it slow!
Current tank 260g FOWLR.
Fish: Moorish Idol, Powder Blue Tang, Hippo Tang, J Emperor Angel, 3 Chromis, 2 Black & White Clowns, Yellow Tang,
