SPS suck

[AndyL]

So anyone care to explain how to avoid RTN?

Thought I was doing really good, my dozen or so frags were starting to colour up again, and were looking good. 3 of nicer milli's were growing noticeably each week...

Then @ lights on this morning, those 3 millis were pure white. Didn't seem to effect the others..

Why would all the millis (save one - of course it wasn't anything overly nice even before it hit the tank) have RTN'd? Nothing changed, nothing dosed.
