Tank is 6 week but when was the bta added? Probably at week 2. A bta don’t bleach overnight. a 5 gallon tank? Just keep changing water everyday. Change water after you feed. Change all day long if you must. 5 gallons is nothing in water and salt vs saving your tank. Do this til you finish cycling. Nitrite at 0. Every time you see the nem deflated I would change water. Let it suck in new clean water. And you lights probably no good. Since it’s 5 gallon you could put it by a window and let it have natural light. Good luck.
