i poured in a bottle of bio spira in monday night and have tested ammonia twice a day since then, It has been at O for 4 days now. When would it be safe to add one fish? i was thinking i would put my B+W ocellaris in there first.
You are supposed to add some fish at the same time as biospira. You need a ammonia source which will be the food you feed the fish etc.
You can also add household ammonia to get the cycle started. If you used biospira the bacteria is already there, now you need to feed it.
Biospira usually cycles a tank in a day or so. I have used it many many times with consistent results.
