I just ran my sponges in my cycled tank for 10 days. Put it in my 3g and never showed ammonia. Did that twice.
Is this question directed at me? No, these were completely new tanks. I've had VERY weird readings. 3 days ago i had .25 ammonia & no nitrites, yesterday 0 on both & no nitrates or so low they don't register. My 10g did the same, one day 0 across the board, then ammonia, then nitrites for a few days then back to 0 then it'd start all over again. So I just keep testing & hoping it'll end one day.
