Good Morning RTN

[sumpfinfishe]

I hear ya! gonna do another 10gl once its up to temp and then another 10gl in a few hours. Would the rtn event over night have caused the NO3 to spike? Or do you think there is something else im missing, like i said everything was fine two days ago and the NO3 wasnt reading a thing. The only other thing i can think of is i got a few frags off a fellow reefer last weekend and his system was polluted with high nutrients but i did not add any water from that system into mine.
