Spring coral losses

[michika]

A week, or two ago, I lost a new colony, a mille, and half of a much older colony, a deep water pieces that I've had for almost a year.

I was using IO, which I loath with a passion, at the time of the RTN (mille) and STN (deep water). I ended up unplugging both my reactors, Ca and Kalk., and it stopped. I've tracked my parameters for years with an excel spreadsheet and every year around this time I have RTN/STN. The only consistent factor year after year is the water. Always run through RO/DI, however its always occured just after a warm spot.
