TX Reef this is fine info, however, the truth of getting rid of it is not to blow it off to start a new batch somewhere else. If you syphon it, it is gone. For awhile, but you still need to find out where it is coming from, yes! Do all of your perameters......did something die, and you just don't see it? Old light bulbs...even out of a new lights if bought off the internet, who knows how old they really are. All this matters, but syphoning is the best option for now, until you can determine where it is coming from.
