This is exactly why I "preach" redundancy all the time, and so many people ignore it, or plan a future resolve. Most of the time they sneak by without any problems (which encourages others to walk the line), but the unlucky ones like you get dragged through the flames.

Your RO/DI reservoir was 37.5% of the system volume. One of my "redundancy rules" is that an ATO reservoir is never more than 10% of the system volume (and never, ever, EVER attached to an RO/DI system which provides an unlimited supply of RO/DI). A full 10% addition of RO will reduce salinity from 1.026 to 1.024 which isn't enough of a change to affect most corals - even SPS. Something to consider for your future tank, so even if the reactor (or something else) failed and dumped system water out, the salinity wouldn't drop too far.

I have one of your SPS, I'd happily send you a big frag when you're ready.

Any yes Mindy, don't I know the reservoir was too big. I was lazy and complacent. This was a temporary arrangement, so I didn't practice my due diligence. My SG was definately lower than 1.015 which means my system volume calculation was off, but in a small system like that miscalculations are definately magnified.

Ah crap...edit and spell check. I DID know the reservoir was too big. I was complacent and lazy. In the haze and stress of recent events, it also just occurred to me that while I normally ran a 33 reservoir I had switched to a 55 reservoir when we went on vacation for a week the last week of August. My old display was a 125 with a 45g of water in a 90g sump. Either way...hopefully everyone else learns from my errors and strive to be more diligent in their reef keeping practices. Bad things don't just happen to "other people". We are all susceptible to disaster, and I should have known better. Nobody to blame but myself.
