Selective rtn

Ugh. The salinity drop would do that - that's a huge drop. That would also cause a huge alkalinity drop (as well as other parameters). Depends how quickly it got that low, how long it was that low, and how quickly you raised it back up.

It dropped over 2 nights I think. Never bumped all up after incedent. Let salinity raise itself very slowly. Still in process. Appears to have stopped. {knock on wood}.
