I have been fighting a cyno problem the past week. I have been sucking it up and brushing it off my lr
. Last night I lost my yellow tang. I checked my water and the ammonia was at .25. Im guessing this is why I lost the tang. All my levels were fine prior to messing with the cyno. So what is my best way to lower the ammonia level. I will be doing a 15 gal
change today. Does carbon help lower the levels? Any other tricks ?
